ChainBrain app for iPhone and iPad

ChainBrain is an infuriatingly simple, and difficult, brain training* memory game for all ages.

The aim of the game is to memorise a chain of numbers against the clock. By the time you are Level 6 Ninja, you will be able to recall a 15 digit number. You can learn and practice new memory techniques on your own, or you can upload your best times to the global Game Center Leaderboard and compete with your friends - and the rest of the world!

Who has the quickest memory in your group of friends? Who is the quickest learner in your family?

With an ergonomic, retro design, you can play ChainBrain anywhere and at any age. If you can use a calculator (remember those?) you can play ChainBrain. To help you through the six levels you start with three lives - which you can use for an extra 20 seconds game time, and a second look at the number. You win an extra life for each of the first five levels that you complete, as well as a star to mark your progress.

You dont need lives to play the game, but if you want some extra ones to get you to Level 6, they are available as an in App purchase.

Once you get to Level 4, the "LevelPicker" is unlocked, so that you can go back and improve on your earlier times. You will be surprised how much better you do second time around. Once you have completed Level 6 (the Ninja level) you can compete for top spot on the global Combined Leaderboard. Who in the world will complete all 6 levels in the quickest overall time?

Devices
Designed to work with iPhone 4s and later, iOS 9.1 to 13.x and on iPads in portrait "iPhone" mode.

Note: ChainBrains "Lives" are what Apple describes as "Consumable" purchases and this is what Apple says about them: "Youll need to buy these items every time you want them, and you cant download them again for free. If you remove and reinstall an app, or install an app on a new device, you might lose your consumable purchases." So if you lose or change your device you may need to make another purchase. We have kept the price to the lowest possible level available on the App Store so your risk of loss is quite small. If you do choose to buy extra lives we are grateful for your support.

The training effects of playing the game may be limited to the single task of memorising a chain of numbers. But it is still fun!
