Blindfold Color Crush: Over 20 Gem Packs

At least once a month, Blindfold Color Crush fans suggest new sound packs.


Color Crush is an audio version of Candy Crush, and is one of the most popular Blindfold Games.  You try to remove as many similar gems as possible – where each gem has a unique sound –  by swapping adjacent gems, to get 3 or more similar gems in a row.  The more gems you get in a row, the more points you score.  Once you’ve scored 50 points, you move up to the next level.

Initially the game had 4 categories: gems, colors, numbers and animals.  One player wanted dogs, another wanted cats and a third asked for flowers, so I created a Pets and Plants Pack.

Each month, over the past two years, I’ve added another pack: Sports Teams Pack (football and baseball), Science Fiction Pack (Star Wars and Harry Potter), Fun Sounds Pack (bells, funny sounds and musical notes), Fantasy Movie Pack (Transformers, X-Men), Everyday Sounds Pack (such as opening a door or an alarm clock),  Candy Pack (popular candies), Funny Voices Pack, Months and Holidays Pack, Animated Movies Pack, Olympic Games Pack, Bird Songs Pack, Minerals Pack, Vegetables Pack, Fruits Pack, Fabrics Pack, Royalty Titles Pack, Merry Christmas Pack, Vehicle Sounds Pack, Musical Instrument Pack, and the Ducks, Geese and Swans Pack.

Since each pack has dozens of sounds, and a level uses only 7 of those sounds, you always get a random selection of sounds on the level.  You can set the game to pick the pack for each level randomly; as you move from level to level, the sounds you must match are always a surprise.

Based on advice from game fans, you can now restrict which packs to use.  Some people purchased many of the packs, and they wanted to customize the game to use only  the newest packs.

Blindfold Games: One Boy’s Story

I received this email from Stuart Beveridge. who works with visually impaired children in Scotland.

xBox control

In April, I began working with an eleven year old boy who had lost his sight last year. He was playing soccer with his friends, fell while chasing the ball and was rushed into hospital.  He had suffered a brain infection from the fall and was in a coma.

When he woke up, he had lost his sight and speech. After several months of speech therapy, he regained his language skills, but his sight would not return. His favorite activity – xBox video games – was no longer possible: those games are not accessible to blind people.  The boy’s parents contacted me for help, and I immediately thought of the Blindfold Games.

“I first showed him Blindfold Dominoes; he was struggling to master the basics of VoiceOver on his iPhone, and was often lost when he was trying to navigate the different screens.  The challenge was to find a simple way of teaching him the basics and giving him the confidence to perform the gestures more accurately and effectively. “Blindfold Dominoes, come on down!”

We did a full lesson on Dominoes, encouraging him to play the game when he could. I emphasized that this game, once learned, would give him the grounding he needed to enable him to navigate and use basic VoiceOver gestures successfully.

Two weeks later, the change in him  was unbelievable. Not only did he master the game, but now listens to YouTube for entertainment, sets reminders for his school work and hospital appointments, and uses FaceTime to keep in contact with his friends.

Another element of Dominoes is the two finger double tap gesture, which is used to “pass” when you can’t play a domino. VoiceOver uses this gesture to play and pause music and is a quick way to answer or end phone calls. Without Blindfold Dominoes, I don’t know how he would have managed; in his words: “it makes the iPhone less boring!”

I have just introduced him and his visually impaired friends to Blindfold Bowling. It’s a step up from Blindfold Dominoes, and he’s learning the sounds, audio cues and feedback from the game. Within ten minutes of playing, they were competing with each other for a bag of Mars Bars.  All went home with smiles on their faces.

Your games have transformed his life.  He realizes that he can still have fun playing games and participate in social activities with all his friends: sighted and visually impaired.

Blindfold Word Search

Most people played word search puzzles when they were young; in a square grid of random letters, you have to find words.  For example, in the following, you have to find the words DOG, CAT and MICE:





The word “DOG” is found in the second line, starting at the second letter.  The word “CAT” is found in the third line, starting at the first letter.  The word “MICE” starts at the fourth letter of the first line, and reads down for 4 lines.

I was asked to create a Blindfold Word Search game of varying complexity, allowing people of all ages and skills to solve the puzzle.

The simplest variant of a word search puzzle is to only hide words from left to right, since people normally read from left to right.  The words “CAT” and “DOG” are hidden in the above puzzle that way.  A little more complex is to hide words left to right, and right to left, like the word “GOAT” in the bottom line.

Once you get good at that, the game gets more complex by including words that are hidden vertically as well as horizontally.  The word “MICE” is hidden top to bottom in the fifth column, and the word “BEAR” is hidden bottom to top in the last column.

In all of the examples so far, letters were only used in one word.  To make the game a little more difficult, some words can share letters.  For example, the letter “C” is used twice: once for the word “CUB” in the first column, reading up, and the word “CAT” mentioned before.

The highest difficulty is where words can run diagonally, from the lower left to the upper right, or from the upper right to the lower left, or from the lower right to the upper left, or from the upper left to the lower right.  In the about example, The word “SIR” starts in the third line, fourth letter, and reads up to the right.

In Blindfold Word Search, you are told which seven words to find; your task is to find them in the grid.  You can adjust both the number of words to find, and the maximum length of a word.

Each month, we create another theme-based word puzzle.  The basic game comes with numbers, months, dogs and cats.  In May, we created a food theme including vegetables, candies and fruits, and numbers.  In June, we released a sports pack for baseball, football and hockey, and a geography pack including countries, states, state capitals and world cities.

Blindfold Hearts and Spades

After I created Solitaire, Crazy 8’s and Uno (called Blindfold Wildcard), I started getting requests for every type of card game.  Since I had played both Hearts and Spades in college, I created those two games first.

picture of card suits

I think back fondly to having a major test in my 8:30 AM class, and realizing I needed only 3 hours to study.  I would join a hearts game at 9 in the evening, knowing I still had 11 and a half hours to study.  At 2 AM, I glanced at the clock and kept playing, trying to “shoot the moon” or somehow win the next round.  After all, I still had about 6 and a half hours to study.  By 3:30 AM, I knew I needed to quit soon, and start studying.  By 5:00 AM, I stopped playing, opened the book, and promptly fell asleep.  I awoke 15 minutes before class, ran to the classroom, and hoped for the best.

Hearts is a trick taking game, which you want to win hands with as few Hearts as possible, unless you “Shoot the Moon” by winning every heart and the queen of spades.  There are several strategies for winning at Blindfold Hearts, including Bleeding Spades, Defending Spades, Maintaining Hearts, Achieving Voids, and, of course, counting cards.  Your computer opponents use one or more of these strategies, and it makes for a fun game.

Spades is a bit more complex than Hearts, in that there is a bidding phase, and a trick taking phase, and your opponents try to stop you from winning the number of hands for which you bid.  Blindfold Spades offers game varieties including Rule 3-B Spades, No Over Spades, Quicksand Spades, 7 Tricks or higher Spades, Cut-Throat Spades, Whiz Spades, Mirror Spades and Fredieu Spades.

Blindfold 3D Tic Tac Toe

Dianne Brauer,  who writes the Perkin’s Path To Technology blog, asked me about which games were best for teaching grid-like concepts.

tic tac toe board

She wrote: “I really like Blindfold Search, Blindfold Word Biggle and Snakes and Ladders; however, these games do not encourage spatial concepts and mental mapping as the locations are not labeled and students are randomly moving through space without truly identifying where they are in space. Snakes and Ladders is closer to knowing where you are (as the game tells you the number of your spot and players have perimeters because they start at 1 and go to 100).  However, players do not know where the ladders or snakes are unless they land on a ladder.   Mental maps are not developed with this game, as the players do not have enough spatial information and they do not need spatial information in order to be successful with the game.”

Dianne suggest I create a 3D Tic Tac Toe game.  Quoting her, “Tic Tac Toe is very easy.  I used to challenge my students to play a mental game of 3D tic tac toe.  Ironically, my blind students quickly learned the game but my sighted friends had trouble getting the 3D part!”

Blindfold 3D Tic Tac Toe is now available.  It’s played on a 3 row by 3 column by 3 level board, and you can get three-in-a-row on any of the levels, or between levels, such as the same position on each level, for all three levels.  For example, the A1 slot on the top level, middle level, and bottom level.

You can vary the skill of your computer opponent based on how many moves “ahead” your opponent looks, and at the higher skill levels, it becomes quite challenging to win.

Blindfold Pinball

When the first visually impaired person asked for a pinball game, I didn’t understand why he would want such a game.  By the tenth request, I started thinking it was a good idea.  After 25 people asked for it, I decided to do it.


From what the blind testers told me, a pinball machine is fun because the sounds are interesting, and, except for knowing when to push the flippers, sighted people have no advantage in playing pinball.  Ball movement is random, and except for trying to tilt the machine, you have very little control.  I knew that when I built the game, I would need to give audio cues so a blind player knows when to push the flippers.

I started by creating a pinball machine with about 8 bumpers, and a left and right channel for the ball to fall into, that leads to the left and right flippers.  To fire the ball, you drag one finger from the top to the bottom, as if you are pulling the launch plunger.  You hear clicks as you pull the plunger, and the ball is fired to the top of the machine, and bounces around for a while.  You hear the clacks,  clangs, dings and dongs, as the pinball hits each bumper and scoring points.

When a pinball rolls into the flipper channel, and is headed for the flippers, the game counts down for you, so you know exactly when to press the flipper button.  Just prior to the flipper, the game says “three”.  When the ball touches the flipper, the game says “two”, and when its at the tip of the flipper, the game says “one”.  You tap the screen, and the flipper shoots the ball back up to the top again.

Just like a real pinball machine, the more you score, the more extra balls you earn.  If the pinball is rolling down the middle of the machine,  just between the two flippers, there’s nothing you can do.  And if the ball gets stuck, just shake the phone a little, to nudge the ball back into play.  If you shake the phone too much, you get a TILT, and you lose the game.

I created several pinball machines, where the overall bumper layout is the same, but the bumper sounds were different.  As of this blog, the game has 13 different machine sound packs, such as animal sounds, outer space sounds, rude body sounds, scary sounds, sailboat sounds, wild west sounds, and funny voices.

Blindfold Fireworks

One of the simplest games I’ve built was inspired by watching and listening to the July 4th fireworks last year.  Since July 4th is just around the corner, Blindfold Fireworks should become popular again.

fireworks display in night sky

Here’s what one person told me: “I love the Blindfold Fireworks. I enjoy conducting my own audio fireworks display. This is awesome! I also enjoy the sounds as the rockets fly through the air.”

The game is so simple, even a toddler can use it.  Each time you tap on the screen, you hear a short explosion, about two to four seconds long.  Tap with two fingers for a longer explosion.  Swipe up for a short whistle or rocket launch.  Swipe down for a longer whistle and rocket launch.

Swipe left to ignite a sparkler, and swipe right to drop that sparkler into a bucket of water.  Fire safety, after all, is important.

Listen to this 30 second display put together by a Blindfold Fireworks expert:

Once your show is over, you’ll hear the crowd scream and applaud your fireworks show.  To download the app, tap here:


Blindfold Games: Thank You e-Card (Updated)

I just received this audio eCard sent with Blindfold Greeting from Lydia A.  It’s nice to hear from the game fans – her card is about a minute and a half minute long.

Thank You Note

Listen here:

Another fan, Debbie C.,  wrote me saying “I am totally blind and reside near Melbourne, Australia. I recently purchased Fireworks and love it! Today, after having trialled Oppoly, I bought the bundle.  I like the choice of country (for the game board layout). That is a good initiative!”

I get a few “Thank You” emails like these each week.  If you like the games, please let me know.  If you don’t, tell me what bothers you, and perhaps we can collaborate and improve them.

Blindfold Monopoly: What’s a good trade?

The game that was requested more than any other game, when I did a survey about a year ago, was Monopoly.

Monopoly banker

For those of you living under a rock, Monopoly is a board game that originated in the United States in 1903 as a way to demonstrate that an economy which rewards wealth creation is better than one in which monopolists work under few constraints and to promote the economic theories of Henry George, and in particular his ideas about taxation.  Since the board game was first commercially sold in the 1930s, it has become a part of popular world culture, having been locally licensed in more than 103 countries and printed in more than thirty-seven languages.

With many games, I research open-source games, and look at the programming code written by other software engineers.  I study how they approached the game on a computer, such as Windows or Mac.  Sometimes a programmer had a great idea on how to present the game, and I can translate what they’ve created into an audio equivalent.

With Monopoly, the game rules are straightforward, the board layout is well known, so other people’s programs didn’t really help.  Almost all of the games I found were designed for people to play against each other; I wanted to find one where you played against a competent computer opponent.  I evaluated over 30 different open source Monopoly programs, and while some of them did let you play against a computer, it played horrendously.

I stumbled upon a master thesis written about 20 years ago, where the researcher came up with strategies for a greedy player,  an evil player, a cheap player, an extravagant player, and for fun, a stupid player.  The differences relate to what types of properties they collect, how often them build houses, how often they mortgage properties, and how they decide which properties to trade.

When I started testing the game, called Blindfold Oppoly, I let you pick which types of players are in the game.  The testers told me that the players were too predictable, and they found it easy to come up with a strategy to win against each player type.

I created a “wise” player that took the best features of each of the four player types, and randomly set which tendencies each computer player would have.  Most times, the wise player makes the best possible move, but sometimes he reverts back to a tendency.  That made the game far more interesting.

While I’ll describe some of the features of the game in another blog, what I found fascinating was reading blogs about when to how to make a good a trade in Monopoly.  Apparently, a trade only makes sense if you end up with a monopoly with rents higher than your opponent.  If you need a monopoly, and you end up with lower rents in the trade, you must get sufficient additional cash to handle landing on their hotel several times.  In addition, it makes sense to mortgage everything you own to achieve your monopolistic goals.
