Duel SIM is part of the Duel series — games built around one idea: your phone as a board game. Two people, same room, one device between them. No online mode, no matchmaking, no notifications. Just the game and whoever's sitting across from you. Not ready to face a real opponent yet? Two built-in AI modes let you train first — and show up prepared. Duel SIM is a two-player abstract strategy game rooted in Ramsey Theory — the mathematical field that proves some patterns are unavoidable. OBJECTIVE Players alternate drawing coloured lines between dots on a circular board. The player who completes a triangle in their own colour loses. Simple rule. Deep strategy. GUARANTEED WINNER By Ramsey theory, on a board of 6 or more dots a single-colour triangle MUST eventually appear. The game always ends — stalemates are mathematically impossible. GAME MODES • Local Duel — two players, one device, face to face • vs AI Trainer — hone your strategy against a heuristic opponent • vs AI Master — challenge the minimax engine for a serious fight SETTINGS & DEPTH • Board size: 6, 7, 8 or 9 vertices — more dots means longer, more complex games • Partial Start — skip the quiet opening; jump straight into the tense endgame • Helper Lines — toggle available-move hints on or off • Match format — first player to reach a target score wins the match • Custom player names CLEAN & FOCUSED No ads. No accounts. No internet required. Pick it up and play. HOW TO PLAY Tap any dot, then tap another to draw a line in your colour. Avoid being the player who closes a triangle. Force your opponent into doing it instead. --- A modern take on the classic pen-and-paper game of SIM, reimagined with neon visuals and a smooth touch interface. Part of the Duel series — turning phones back into board games.
