About Slinky
Slinky is a logic puzzle where each move you make shapes the rest of the level. You travel across a grid of numbered tiles, keeping an eye on values that drop toward zero, because a tile that runs out ends your attempt. Red and yellow tiles need to be turned green before you can clear the stage, so every route you pick should be checked for dead ends before you commit.
The puzzles grow more involved as you progress, and early choices can come back to matter later. Slow down, sketch the path in your head, and test a few options before moving. If you enjoy games that reward patience and planning, Slinky gives you plenty of tricky paths to work through, all playable free in your browser.
