Play online instantly — no account needed. TapXO brings eight board and puzzle games together in one free app: Tic-Tac-Toe, Connect Four, Chess, Checkers, Reversi, Word Search, Liquid Sort and Crossmath. Play the computer, pass the phone to a friend at the same table, or find an opponent online in one tap.

★ EIGHT GAMES IN ONE APP

• Tic-Tac-Toe — play the classic 3×3 game, or try bigger boards from 4×4 up to 6×6. Try the default 5×5 board with four in a row.
• Connect Four — drop your discs into the grid and connect four in a row across, down or diagonally before your opponent does.
• Chess — full chess rules, including check, checkmate, stalemate, castling, en passant and pawn promotion. A good way to learn chess against the computer, then test it online.
• Checkers — international-style checkers with forced captures, backward captures and flying kings. Plan your jumps and crown your pieces.
• Reversi — flip your opponent's discs, fight for the corners and finish with the most discs on the board.
• Word Search — find the hidden words across 15 categories, from animals and food to space and music, with hints when you are stuck. Race another player online on the same Word Search puzzle: first to find every word wins.
• Liquid Sort — 90 color-sorting levels, six glasses, hidden colors and relaxed or timed play.
• Crossmath — fill crossing equations in four difficulties, with hearts, hints, undo and daily puzzles.
