The engine picks a good move and says why: it captures, builds pressure, takes the centre, joins a group, or leaves the edge.
Sumito is a game of push and position for two players. Slide lines of up to three marbles, outnumber your rival, and be the first to push six of their marbles off the edge.
Tap 1 to 3 of your marbles in a straight line. A green dot means that marble can move.
Tap a glowing dot, or swipe. The whole line moves one space — along the line or sideways.
More beats fewer: 3 push 2 or 1, and 2 push 1. Equal lines cannot push.
A marble pushed past the edge is out. The first player to push out 6 wins.
A compact group has more moves and fewer weak edges. Lonely marbles get pushed.
Central marbles can move in six directions. Edge marbles are one push from danger.
Three beats two. Two beats one. Equal lines never move each other.
