Unique Space Station Mechanics

Expanding Grid System

The metallic space station starts at 6×6 and expands to a massive 8×8 grid when corner bombs detonate. Four space station sections surround the main field, acting as tunnels for bird movement. At maximum field size, space portals appear in corners allowing birds to teleport between positions, creating complex collection paths through the cosmic arena.

Ten Feature Symbols

Pirots 4 features an intricate system of ten distinct feature symbols: Upgrade (increases gem levels by 1-3), Upgrade All (boosts all four colours), Wild (substitutes at current payout level), Coins (multipliers up to 4000x), Bonus (triggers 5 free spins), Super Bonus (maximum grid bonus), Transform (changes gem clusters), Spacecorn (bridges empty spaces), Black Hole (randomises field), and Alien Invasion (activates Space Bandit duels).

Advanced Features

Alien Invasion Feature

When Alien Invasion activates, the Space Bandit appears and collects symbols column by column in random order. The Space Bandit engages birds in space duels—winning increases the spaceship multiplier and removes defeated birds, while losing ends the invasion. If the Space Bandit defeats all birds, it collects remaining symbols, applies the accumulated multiplier, places random coins, and returns the birds for a massive payout opportunity.

Lost in Space Game

Triggered when birds collect ALL symbols during a Spacecorn feature, Lost in Space plays on the full 8×8 grid with one bird in each corner. Starting with 3 drops, the counter resets when landing coins or bridges. Birds collect horizontally or vertically adjacent coins using bridges to cross gaps. Multiple birds linked by the same coins sum their values for the final payout, creating intricate collection strategies.

Power Clash

When three or more birds become horizontally or vertically adjacent, they collide in one position creating a Power Clash. This removes gems in a 5×5 area and scatters birds horizontally, vertically, or diagonally. Birds automatically collect corner bombs, Alien Invasion symbols, Black Holes, coins, and bonuses along their path. Stones removed during the scatter do not count toward the collection counter, making Power Clash a strategic advantage.

Corner Bombs & Tunnels

Four corner bombs sit at the inner corners of the space station, each receiving a random bird colour at round start. When a matching bird collects at a bomb position, it activates and detonates after collection ends. Detonation removes all birds, clears gems in a 3×3 area, removes the connected space station section, and expands the field. The removed sections become tunnels allowing birds to pass through when collectible symbols appear at entrance and exit.

Frequently Asked Questions

Each bird collects gems of its corresponding colour (red, purple, green, or blue) and ALL feature symbols regardless of colour. Birds move only horizontally or vertically to adjacent symbols and cannot finish collection on a wild symbol. They continue collecting until no further movement is possible, with each colour having seven upgrade levels affecting payout values.
Pirots 4 offers a maximum win of 10,000x your stake. This can be achieved through combinations of high-level gem collections, coin symbols with multipliers up to 4000x, successful Alien Invasion multipliers, or extensive Super Bonus rounds on the maximum 8×8 grid. When the win limit is reached, the round ends early and accumulated wins are paid out immediately.
The game field expands when corner bombs detonate. Each of the four corner bombs is assigned a random bird colour at the start of each round. When a bird of the matching colour collects a symbol at that bomb's position, the bomb activates. After collection completes, it detonates, removing gems in a 3×3 area, eliminating the connected space station section, and expanding the field toward the maximum 8×8 size. At maximum size, space portals appear in corners for bird teleportation.
Pirots 4 offers five X-iter modes: Bonus Hunt for €3.00 (4x bonus activation chance), Alien Invasion for €25.00 (guaranteed Space Bandit feature with super bonus on activation), Lost in Space for €50.00 (direct entry to the corner bird collection game), Bonus Game for €100.00 (regular bonus with 5 free spins), and Super Bonus for €500.00 (maximum 8×8 grid where all upgrade symbols upgrade all gem colours). All modes maintain the same 94.0% RTP.
Each gem colour has seven upgrade levels with increasing payout values. Red gems range from 0.10 to 30.00, purple from 0.10 to 15.00, green from 0.05 to 10.00, and blue from 0.05 to 7.50. Upgrade feature symbols increase gems by 1, 2, or 3 levels (maximum level 7), while Upgrade All symbols boost all four colours simultaneously. In Super Bonus mode, every upgrade symbol upgrades all gem colours, dramatically accelerating value growth.
