About Slime Siege

Slime Siege is a free castle defence game. Waves of gooey slimes are bouncing down the hill toward your castle, and your archers fire wherever you tap. Tap a slime to send an arrow at it; small slimes pop in one hit, big slimes take several, armoured slimes wear helmets, and green splitter slimes break into two small ones. Fast blue slimes zip down the path, so deal with them first. Every slime that reaches the castle wall bites a chunk out of it, and when the wall's health runs out the castle falls. Popping slimes earns points and coins, and the waves keep coming, bigger and faster each time. When things get busy, use the bomb: it pops every slime on the screen, then needs time to recharge. Between waves, the wall repairs a little. Lose the castle and the game is over, but you can resume once with the wall rebuilt. Everything is cute and squishy, with no blood, so it suits everyone. Slime Siege is perfect for quick taps on a phone or clicks with a mouse.

How to play

  • Tap or click a slime to shoot it
  • Big and armoured slimes need several hits
  • Tap 💣 to pop every slime (recharges)
  • Don't let slimes reach the wall

Tips

  • Shoot the fast blue slimes first
  • Pop splitters early, before they split near the wall
  • Save the bomb for crowded moments
  • Slimes closest to the wall matter most
