Chess just got a roguelike, and it has been in your phone since Friday. Gambonanza, the turn-based chess builder from solo developer Blukulélé, launched globally on Steam, iOS and Android on May 1, 2026 — and after a Steam Next Fest demo that pulled in over 170,000 downloads, the full release is finally here. It costs less than a coffee, runs on practically any device, and turns the world's oldest strategy game into something you have never seen before.
The pitch is deceptively simple. You play chess on a smaller-than-standard board, but every run gives you access to over 150 Gambits — modifiers that bend the rules of the game in ways FIDE would absolutely never approve of. Some Gambits supercharge a single piece. Others force opponents to skip turns. A few let you spawn extra knights mid-game. The combinations stack, escalate, and eventually break the game in the most satisfying ways imaginable.
Why It Hits Different on Mobile
This is a turn-based game on a small board. There is no twitch reflex requirement, no precision aiming, no need for a gamepad. Mobile is arguably the better platform for it — every match is naturally bite-sized, the touch controls map perfectly to chess piece movement, and you can pause mid-run without consequence. Stray Fawn and Sidekick Publishing clearly understood this, releasing the mobile and Steam versions on the exact same day rather than treating phones as a port afterthought.
The presentation leans into a vibrant pixel art aesthetic with a subtle CRT filter overlay, and there are mini-games sprinkled throughout — slot machines, pachinko-style bonus rounds, gachapon pulls — that exist purely to add chaos to your run. It is the kind of design philosophy you only get from a solo developer who is making the game they personally want to play.
Pricing and Reception
Gambonanza is priced at $14.99 on Steam with a 35% launch discount that brings it down to $9.74. Mobile pricing is similarly modest, and there are no microtransactions, no ads, no battle pass — just the full game for one purchase. Critics have been overwhelmingly positive, with Checkpoint Gaming calling it a checkmate of a debut.
If you have ever wanted to play chess but found it intimidating, or you have always loved chess but thought it could use more nonsense, Gambonanza is genuinely the best version of both fantasies. May 1 was a quiet launch day. The game has been climbing the charts ever since.
