Show HN: Schmess – chess with no turns; pieces freeze on cooldown after moving
schmess.comSolo dev here. Schmess is chess with the turn structure removed. Both players move whenever they have a free slot, and every piece freezes on a cooldown after it moves. It's on a half board, with 100+ puzzle stages. If two people played this over a physical board they'd scrape each other's fingers raw - that's roughly the tempo.
Plays in the browser, no signup. 29 stages free, one-time unlock for the rest ($3.99 / Rs 149). No subscription, no ads.
It's the second of a few small-board variants I'm building (halfchess was the first, more coming). Building a chess engine for a game with no turns turned out to be the hard part - I've put the war stories in a comment below.
Nice job. There was actually an attempt to build a physical, real-time chess prototype back in 2015 that you might also find interesting, called Dengekisen: Speed Chess.
In that version, each piece had its own small cooldown timer that had to expire before you were allowed to move it again.
I love the chessboard design on the table top. I will love to do in schmess chessboards.
I wonder if adding a "dark souls" mode, where each move is delayed by a wind-up (or perhaps slow movement?), might result in more strategic gameplay approaches.
Agreed-adding a wind-up delay would make gameplay significantly more strategic.
From an engine and state-space perspective, a "Dark Souls mode" creates a massive challenge.
Explosive Search Tree: Because moves overlap in time, evaluating positions via traditional brute-force depth/breadth search becomes nearly impossible. The state space expands exponentially (or infinitely, without cooldowns).
Strategy over Calculation: Because an AI or player can't brute-force every micro-timeline, win conditions rely far more on high-level positional control and timing anticipation rather than raw calculation.
Endgame Dynamics: Cooldown management would dominate the endgame. It could either make drawing much easier or completely alter fundamental checkmate patterns (like King + Rook vs. King).
Great concept to think through!
