Pirots 4 slot review

Pirots 4 is the fourth numbered game in ELK Studios’ Pirots series, released in July 2025, and it puts the four parrots in space suits aboard a space station. It uses the CollectR system on a 6x6 grid that can open up to 8x8, with birds collecting matching gems instead of paying on lines. The maximum win is 10,000x stake.

How Pirots 4 plays

Every spin drops gems in four colours onto the grid along with the birds. Each bird collects adjacent gems of its colour and keeps going until nothing else matches. Gems have seven levels, and upgrades raise them. The feature symbols on the board are:

  • Coins: pay a cash prize when collected.
  • Wilds: stand in for any gem at its current level.
  • Upgrade and Transform: raise gem values or turn nearby gems into a bird’s colour.
  • Spacecorn and Black Hole: let birds cross empty space, or pull in and move symbols and birds.

The grid grows through corner bombs. When a bird reaches one, it explodes and clears a 3x3 area, removing part of the space station and opening the board towards 8x8.

Alien Invasion, Lost in Space and free spins

Pirots 4 has three bonus routes:

  • Alien Invasion: when a bird collects the Alien Invasion symbol, a Space Bandit arrives, collects gems and battles the birds, adding to a multiplier while it wins.
  • Lost in Space: clearing every section of the grid starts this coin game on the 8x8 grid with a bird in each corner. It begins with three spins, and a new coin or bridge resets the count.
  • Free spins: three scatters award five free spins that keep the grid size, collection meter and upgrades. A Super Scatter starts a super version on the full 8x8 grid.

The Space Bandit is the twist that sets this game apart: the birds can lose a battle as well as win one.
