iPhone
Send a friend a link and Expert plays them the way you play. Beat him and they crack one of your habits. They don't even need the app to try.
Rock paper scissors against a computer is usually a coin flip. This one isn't.
You play Expert, an opponent that watches every round you throw and plays against your habits. It follows the sequence of both players' moves, because people react to what you just did; watching your moves alone throws away half the signal.
THE THROW
Press and hold a tile. Two clay hands pump three times. Release on "one" to commit.
Slide your finger to a different tile mid-pump and your throw changes with it. That is the whole mind-game: you get three beats to change your mind, and so does Expert. Let go early and you have fouled the round.
If the gesture isn't for you, turn on Tap to Throw and the whole thing becomes a single tap.
IT SHOWS ITS WORK
Open the stats sheet mid-match and Expert tells you what it currently expects you to throw. It isn't a hint system. It's a read, offered honestly, and you are welcome to use it against him. Throwing the counter to your own tell works beautifully, right up until he notices you doing it.
EIGHT RUNGS
Rung one is genuinely random and never plays its read at all. By rung eight it plays the read nine times out of ten. Somewhere in the middle you start to feel it paying attention, and the game stops being about luck.
WHAT ISN'T IN IT
No ads. No accounts. No sign-in. No internet connection at all. The whole game runs on your device, and nothing you do in it leaves your phone.
Free play, both clay hand sets, the full statistics sheet, and Expert's read are free forever. One optional purchase unlocks rungs four through eight, and it's a one-time unlock rather than a subscription.

New: send Expert to a friend.
Once Expert has watched 30 of your throws, a Challenge button shows up on Home and on the result screen. Pick one of your habits to seal inside the link and send it. Your friend plays Expert as you, first to 3, straight from the link, with nothing to install. If they win, they find out which habit you sealed. If they lose, it stays sealed. Either way they can send the score back, and it lands on your Home screen.
Also in this update:
Practice lets you set Expert's read yourself and play against it, once you've thrown 50 times.
How It Thinks opens up the room. You can see the experts that vote on your next throw, how sure Expert is, and your match history.
Expert still lives entirely on your phone. Sending a challenge puts one link in your hands and nothing on a server.
