"The hardest memory matching app I have ever tried, though I'm not sure why. It made my brain hurt."

Think you have access to your short-term memory? Your subconscious? Do you really believe the conscious part of your mind isn't getting in your way? How much of what you think you know is really just your thoughts lying to you?

Memory Shift is simple. Just match two, three, up to four tiles, just like the classic game.

It's so simple because we provide you with all the answers right at the start, and continue showing you throughout the game. At all times, you know exactly where every tile lies, even when they move. The problem is that it is the subconscious part of your mind that picks up all this information and it is the conscious part that is picking the tiles. One knows everything; the other knows little and often messes up trying to convince you otherwise.

This is the "lite" version of Memory Shift. The full version, purchased from within the app, allows for…

• Saved scores
• Access to the scoreboard
• Access to the Game Center leaderboards

See how much control you have over your own thoughts, your ability to access your subconscious. Your brain knows far more than you think you know.

The trick is figuring out how to get to it.
