From first tap to finish

You play a soft green blob inside a facility that is not friendly to blobs. The aim is to get out. To do that you cross a series of rooms, each with its own hazards.

A good way to think about the game is as a series of small puzzles. Each room asks you to read the hazards, plan a path and carry it out with your jumps. The stretch and squash of the blob gives the movement a bouncy feel, and the floppy disks give you a reason to look into corners. Poki lists the game as released in August 2022 and updated in January 2026, and its page shows a rating of 4.2 from 263,810 votes. Those numbers are Poki's, quoted here only for context. Movement is simple: the left and right arrows move the blob, the up arrow jumps and the down arrow drops down. The twist is in the body. The blob can stretch and squash, and that shapes how you jump and fit through tight spaces.

Sharp spikes are the main danger, so most of the work is placing each jump with care. Hidden floppy disks are scattered through the rooms. They are optional, and finding them rewards looking beyond the obvious path. Poki lists a two-player option for this game as well.

Handy habits

• Look at a room before you move. Finding the spikes first makes the route clearer.
• Use the squash and stretch on purpose. They are part of the movement, not decoration.
• Look for floppy disks away from the main path. They are hidden, so they are rarely on the obvious route.
• Take short, small jumps near spikes. Long leaps leave less room to correct.

Made for

Players who like retro platformers and careful jumping. It uses only the arrow keys, so it is easy to learn. Slime Laboratory suits people who like retro platformers, who enjoy planning a jump, and who do not mind repeating a short stretch. It also works for two players, which can turn a tricky room into a shared challenge. If you prefer slow, relaxed games with no risk, a calmer title may fit better.

What to expect, minus the shine

• Poki shows ads around its games.
• The arrow-key controls suit a keyboard best, so a touch screen can feel less precise for timed jumps.
• Spikes mean repeating a room after a mistake, which can feel slow if you prefer relaxed play.
