Chess Destroyer is like a normal chess game but bigger and some new rules:
the map gets bigger every turn
more enemies come
you can capture an enemy unit by killing it with your pawn unit,
or acquire new ones by completing simple quests appearing in the bottom left corner of the screen

Kill enemy units, find friendly ones, defend the king, and survive as long as you can!

Lore: To escape from death the king had to run from the battleground. with his 2 pawns, he jumped from his chess board onto another smaller one. but it's growing and enemies are coming.

The rest is up to you. good luck!
