SURGESTONES
They see where you play.
Never what. Then it all flips.
Slip a stone in face-down, flip, and watch every line on the board shove forward at once. A two-player strategy game for iPhone and iPad, free to play.

Animated example of one round. Blue and Orange each place a stone face-down. The stones flip: Blue placed a 6 behind its line of 5 and 1, and Orange placed an 8. Every line surges forward one square at once. Blue's line, 12 strong, shoves Orange's line of 3 and 4, 7 strong, back one square, and Orange's 4 falls off its back edge. Blue scores 4.
Blue shoves a 4 off. +4

One stone a round. The rest is reading the person across the board.

Hide your move
Slip a stone, 1 to 10, face-down into your home rows. They see where it went. Never what it is.
-
Watch it all flip
Both stones turn over. Then every line on the board lurches forward one square, all at once.
-
Shove harder
Where lines meet, add up the front four stones. The heavier line shoves the lighter one back. A tie costs both sides a stone.
-
Take their stones
Shove an enemy stone off its own back edge and its value is yours. It's the only way to score, so every point is a fight.
