About Side Effect

Side Effect is a tactical roguelike based on chess. You choose an elemental school and enter an arena, using spells channeled through your pawns to control the board. Each pawn gives spells different effects, so positioning your pieces and planning ahead are central to play. The AI adapts its moves and can be difficult to beat.

Build your spellbook

You assemble a spellbook from 9 schools of magic, gather artifacts and experiment with combinations to shape your play style. You must adapt your spells and strategy to the mechanics of each level.

Play together

You can play with one other person. Combining your spellbooks can change your strategies, and plans may take unexpected turns as the effects of magic and the AI’s actions unfold.
