Take a breather
Games
Four classics for when your head is loud: Tic Tac Toe, Sudoku, Chess and Checkers. Play the computer or a friend on the same phone. Nothing is saved.
Tic Tac Toe
Three in a row. Play the computer (it plays a perfect game — a draw is a win) or pass the phone to a friend.
X to play
X 0 · O 0 · Draws 0
Sudoku
Every row, column and 3×3 box needs the digits 1–9 exactly once. Each puzzle is freshly generated with exactly one solution.
Making a puzzle…
Chess
Full rules: castling, en passant, promotion (to a queen), check, checkmate and draws. Tap a piece to see where it can legally go.
White to move
Checkers
Standard rules: diagonal moves, compulsory jumps, chained multi-jumps, and crowned kings that move both ways. Play the AI (it plays black) or a friend on the same device. Red goes first.
Red to move
Red pieces 12 · Black pieces 12
