KINGSIDE
Chess, Checkers, and Backgammon on a walnut board. $5 once. Nothing else, ever.
KINGSIDE is a board game game. It costs $5 once — a one-time purchase, not a subscription. You can play it in the browser today. iOS, Android and Steam are planned.
Chess + Checkers + Backgammon. Buy once. No subscriptions. No ads. No microtransactions. Local AI, fair dice, pass-and-play, daily puzzles.
Chess, Checkers, and Backgammon — three complete board games on one walnut board. Pay $5 once and play the rest of your life. No subscriptions. No microtransactions. No ads. No daily-puzzle limits. No engagement-manipulated dice. No paywall mid-improvement.
One game, three classics. Every mode is included on day one — solo vs. AI, pass-and-play on one device with someone next to you, daily puzzle, Puzzle Rush, opening trainer, endgame practice, full game history with review. New modes added free.
Chess — full FIDE rules with five named AI personalities you'll actually remember playing: The Pawn (the eager beginner), The Gambiteer (the romantic attacker), The Professor (the positional grinder), The Wall (the fortress builder), and The Oracle (the unpredictable master). 71-position opening book, post-game analysis with eval bar and best-move arrows, threefold repetition, en passant, castling — every rule you expect, none of the dark patterns you don't. 500-puzzle Rush. Daily challenge that varies (mate-in-2, tactics, endgame study, opening line). Your ELO climbs across every game you play.
Checkers — 8×8 American with mandatory jumps, multi-jumps, kinging ceremony. (Yes, jumps are mandatory — it's how the game is actually played. The in-game How to Play sheet walks you through the rules that trip people up.) Three AI tiers. Drag-and-drop or tap-to-move.
Backgammon — full match play with the doubling cube, gammons, backgammons, and the Crawford rule. The AI uses a Janowski-linear match equity table to decide when to double and when to drop — same math the serious players use. The dice are rolled locally on your device, with no server, no manipulation, no engagement-tuned outcomes. When the AI offers a cube, tap "Why?" to see its equity, the take/double threshold for the current match score, and its reasoning.
Designed for the living room, not the algorithm. Walnut-and-gold aesthetic, custom Lichess Maestro chess pieces, real CC0 wood textures, restrained motion (no overshoot or theatrics), warm music that loops without intrusion. Sixteen languages including Hindi, Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, and Urdu.
No internet required to play. No account required. Cloud save if you want it, via Inlet Passport — optional, never gated.
Buy once. Play forever. Three classics. One quiet room.
_Some artwork and music in this game were created with AI-assisted tools._

Why I made it
I wanted chess, checkers, and backgammon in one place, made with the care of a real table — a walnut board, an AI I tuned by hand to play like an opponent rather than a rating slider, and dice you can trust, because backgammon dies the moment you doubt them. It's for anyone who misses playing these games across from someone.
