Green - Play Online for Free! | Poki Game

Green is a minimalist puzzle game by Bart Bonte where the goal is always the same — turn every object on screen the same shade of green — but the trick for getting there changes on every one of the 50 levels. There's no tutorial text; each screen is a small, self-contained riddle you figure out by clicking around until something moves.

Sessions are short: most levels take anywhere from a few seconds to a couple of minutes once you spot the mechanic, which makes it a good fit for poking at one puzzle at a time rather than settling in for a long run. There's no timer and no fail state, so there's nothing stopping you from just staring at a screen until the solution clicks.

Controls

Mouse only. Depending on the level you'll click, click-and-hold, or drag — no keyboard input is needed.

Tips

• Click on everything visible first. A lot of levels hide their working part behind something that looks like plain scenery until you interact with it.
• Stuck on a level? Use the light bulb hint button rather than clicking at random — it points directly at the interaction you're missing.

A good pick for anyone who likes short lateral-thinking puzzles over reflex or timed challenges.
