Doubles Chess is four-player team chess: two teams of two, one board, and both teammates moving at the same time — secretly. Each player commands one half of the board (files a–d or e–h). Every turn, you and your partner each pick one move in secret; they execute simultaneously. You can see THAT your partner has locked something in — never what — until both moves hit the board at once. RULES BUILT FOR SIMULTANEITY • The first move submitted locks in; the second must make the combined turn legal • Escape check as a team: one saving move is enough, judged on the combined result • Two enemy pawns can double-step in one turn — double en passant is real • Pins are real: you play the board as you see it • Checkmate only when NO pair of moves saves the king — strictly harder than normal mate • Pieces that cross the center line change hands: gifting your partner a rook is a strategy PLAY IN SECONDS • Create a room, share the 4-letter code, friends join instantly • No accounts, no sign-ups — pick a name and play • Empty seat? Add a bot with engine-ranked moves • Disconnected? Reconnect and pick up exactly where you were • Resigning takes both teammates. A draw takes all four. Argue accordingly. Bring your favorite partner. Blame them later.

Verdict

The call

The clearest difference is in-app purchases: Driz's Doubles Chess at none against Block! Triangle puzzle's 10. Driz's Doubles Chess also leads on ads (none vs shown) and rating (5.0 vs 4.6). Block! Triangle puzzle's advantage is ratings volume (44K vs 1) and update cadence (weekly vs fortnightly). On price there is nothing between them.
