Why CrossZero

Three pillars. One obsession.

Built for players who want depth, speed, and a fair ranked climb.

Massive Grids

Choose 6×6, 8×8, or 10×10 boards. The bigger the grid, the deeper the strategy.

Real-Time Multiplayer

Global matchmaking, private room codes, and a battle-tested AI when matches are quick.

Competitive ELO Ranking

Earn ELO, chain win streaks, and climb tiers from Bronze to Master.

How scoring works

Every triplet counts. Play the whole board.

Forget sudden-death 3-in-a-row. In CrossZero the board fills completely — every time your move forms a line of 3 matching symbols, you bank +1 point. Highest score when the grid is full wins.

  • +1 per triplet completed

    Each horizontal, vertical, or diagonal run of 3 your move closes adds one point to your score.

  • Multi-triplet combos

    A single well-placed cell can close two or three triplets at once — earning multiple points in one turn.

  • Play until the board is full

    The match only ends when every cell is filled. Highest score wins. Equal scores end in a tie.
