Kingside Break
A chess game where you lead a customizable fantasy army through 1,500 levels of curated puzzles. Face checkpoint commanders in full matches, recruit new races, and customize your hero and army. Key chess concepts encountered are logged in a Sage Ledger for education and future reference.
A FANTASY CAMPAIGN BUILT ON CHESS
March across eight pixel-art realms in a single-player chess adventure. Each campaign level asks you to solve three curated tactical positions. Read the board, find the winning line, and build a lasting record across 1,500 levels and 4,500 puzzles.
Customize your hero and your armies as you move through the levels. Play standard, official-rule chess against checkpoint wardens and generals. Save all 8 realms.
LEARN AND IMPROVE IN CHESS
A Sage Ledger keeps track of real-life chess concepts and strategies encounted in-game and logs them. Players will be able to review the logs, what the concepts are, and replay scenario to reinforce learning. Ledger will also keep track of times the player executes the concept or strategy in-game.
FIGHT FOR EVERY REALM
Puzzle victories carry your army forward, but the road is not tactics alone. Face 75 checkpoint battles in full chess matches against the AI, including eight realm Generals. Win the decisive battle—or earn the right Skip Pass in Skirmish—to continue the campaign. 
BUILD YOUR ALLIANCE
Field seven playable fantasy races, recruiting new allies as the campaign grows. Customize your Hero and Army with Gold earned through play, then bring your chosen look to the battlefield. Cosmetic choices change how your forces appear, never how the chess rules work.
