The basics of play

You guide a soft green slime through a facility full of hazards. The slime stretches and squashes as it moves and jumps, which changes how it fits through gaps.

Sharp spikes are the main danger. Hidden floppy disks are scattered through the rooms, so checking corners and ledges is part of the game. Two sequels, Slime Laboratory 2 and 3, are also on Poki.

Tips for starting

  • Take a moment in each room to see where the spikes are before you move.
  • Jump from the edge of a platform to keep control in the air.
  • Look above and below the main path for floppy disks.
  • Use the down arrow to drop onto lower platforms instead of walking round.

Who it is for

Players who like platformers and are happy to repeat a tricky jump.

Things to weigh

– Poki shows ads around the game.

– Keyboard controls make it harder to play on a phone; Poki lists phone support but the controls are listed as arrow keys.

– Hidden items can send you back through rooms you have already cleared.
