About This Game

OILST is a relaxing puzzle game that explores the surprising geometry of stamping tetrominoes and polyiamonds (their triangular cousins) on top of each other. Move, rotate, and stamp simple shapes to reduce complex grids of numbers down to exactly zero.

The 200+ hand-crafted levels are designed to surprise, delight, and challenge but not break your brain. Puzzles start simple and gradually reveal the depth of the mechanics. Many levels have multiple solutions to explore.

The minimalist graphics together with a soothing soundtrack help you focus and unwind. Settle back, take your time, and enjoy.

Originally made for the 2026 GMTK Game Jam, now polished and expanded into a full game.
