Crownspire

CROWNSPIRE — Draughts Reimagined

Checkers, all grown up. Crownspire takes classic draughts and stacks it with four rule variants, four-player free-for-alls on boards up to 28×28, a self-improving AI, and full online multiplayer — all playable in the browser, offline-capable, on desktop or mobile.

FOUR WAYS TO PLAY

English — the classic 8×8, 12 pieces a side, forward-only men.

International — 10×10, 20 pieces a side, flying kings, forced maximum captures.

Russian — 8×8, flying kings, backward captures, and on-the-fly promotion mid-jump.

Surge ⚡ — Russian rules plus new ways to crown a king, and a king that's as much a liability as a threat. Higher stakes, higher risk.

4-PLAYER MODE

Four colours, four corners, one winner. Play Red, Dark, Blue, and Gold simultaneously across Small (12×12), Medium (20×20), or Large (28×28) boards — up to 85 pieces per player for genuinely epic matches. Choose Standard, Flying-king, or Surge rules for the free-for-all.

AN AI THAT ACTUALLY ADAPTS

Casual, Normal, and Hard difficulty, from loose random play up to full alpha-beta search seven moves deep.

The Learner — an AI that starts at Hard and gets stronger every game you play against it, biasing its future play toward the positions that have beaten you before. Its memory persists across sessions, so it never truly forgets.

ONLINE + DAILY CHALLENGES

Sign in and drop into a live lobby for 2-player or 4-player online games, complete with a move timer, spectating, rematches, and a global ELO leaderboard. Or come back every day for a fresh Puzzle of the Day and Game of the Day, and build your streak.

MAKE IT YOURS

Unlock alternate piece sets and board skins in the in-game store, switch between flat top-down and full isometric 3D perspective, and tune haptics, music, sound, and spoken commentary to your taste.

PLAY ANYWHERE

Installs as a PWA and plays fully offline once loaded — no connection needed for solo or local matches. Works on phone, tablet, and desktop.

Enjoy!
