Read full descriptionHide full description
Chess, but you build your own army. Start with normal pieces. Lose. Earn coins. Buy modifier cards that give your pieces new movement abilities - a Rook that leaps like a Knight becomes a Chancellor. A Bishop that slides like a Rook becomes a Queen. Stack enough upgrades and your pieces become monsters the AI never saw coming. PLAY ā EARN ā UPGRADE ā RETRY Every game earns currency, win or lose. Losing is part of the plan. Spend coins on modifier cards between games, equip them on up to 5 pieces, and go again with a stronger army. The loop is addictive. The power fantasy is real. 10 MODIFIER CARDS ⢠+Knight - give any piece the Knight's L-shaped leap ⢠+Bishop - add diagonal sliding to a Rook or Knight ⢠+Rook - add straight-line power to a Bishop or Knight ⢠+Camel - the Knight's weird cousin: a (3,1) leap ⢠+Knight & Bishop - create an Archbishop ⢠+Knight & Rook - create a Chancellor ⢠+Rook & Bishop - create a Queen from scratch ⢠And more. Stack them. Break things. FAIRY CHESS PIECES Chancellor. Archbishop. Amazon. Centaur. Names you've seen on Wikipedia at 2am. Now they're in your army, doing absurd things on an 8Ć8 board. Every upgrade is a real fairy chess piece with movement rules that have existed for centuries, we just put them in your hands. NO ADS. NO WAIT TIMERS. NO ENERGY SYSTEM. Play as much as you want. Progress is real. Every coin you earn stays. Every card you buy is permanent on your save slot. Built with a custom fairy chess engine. Runs entirely on-device. No internet required.

Verdict
The clearest difference is in-app purchases: Mongjin at none against Heretic Chess's 1. Heretic Chess's advantage is ads (none vs shown) and device support (3 vs 1). On price and update cadence there is nothing between them.
