Bonus Game

Each corner of the space station grid contains a corner bomb, randomly assigned to one of the birds. When a bird collects a symbol positioned on top of a bomb that matches its colour, the bomb is armed. Two adjacent birds have a random chance to perform a Switcheroo when they can’t collect more symbols.

This reset creates a fresh layout, often sparking new chains of collections and big win setups. This mode uses an 8×8 grid with the four birds positioned in corners. Landing coins or bridges resets the drop counter back to 3. Golden upgrade all symbols also display 1, 2, or 3.

Travels through space station tunnels when sections are removed. Slots are one of the most popular types of online casino games. They are very easy to play, as the results are fully down to chance and luck, so you don’t need to study how they work before you start playing. However, if you decide to play online slots for real money, we recommend you read our article about how slots work first, so that you know what to expect.

Diamond Spins Cats

Game continues until drops are exhausted or win cap is reached. Different gameplay mode focused on coin collection rather than gem collecting. These birds physically move around and collect symbols that touch them orthogonally (up, down, left, right – not diagonally). Each bird collects gems matching its own colour, plus any feature symbols it touches. All free drops play at maximum 8×8 grid size with all upgrade symbols affecting all gems.

Space Switcheroo moves one bird to field edge or next collectible symbol, removing non-collectible stones without counter contribution. Charlie’s Extra Chance randomly activates 1-4 corner bombs simultaneously when birds cannot collect further, potentially triggering massive chain reactions. Four circular mechanical devices sit at each corner of the 6×6 grid.

Pirots 4 Casino

If the bonus game triggers during Alien Invasion mode via an X-iter purchase (25x bet cost), it’s automatically a super bonus game. Spacecorn looks like a striped popcorn box with corn kernel eyes. When a bird collects it, Spacecorn fills all empty grid spaces.

The Four Collector Birds and Gem System

Since 2014, they’ve refined mechanics across sequels—Cygnus reached its sixth iteration, Pirots its fourth with this space-themed collector. Their X-iter buy feature became an industry signature. Swedish studio that iterates rather than innovates wildly, perfecting systems over time. A golden letter W that substitutes for any gem at its current payout level. Birds can’t end their collection run on a Wild—if they land on one, they’ll move to an empty position instead. Click on the bet amount in the bottom right corner to open the bet selector.

Alien Invasion Duel Mechanics

Your gem levels and symbol collection progress carry over unchanged. If a bird can collect symbols at both the entrance and exit of a tunnel, it travels through the space station section. Each tunnel can reveal up to two feature symbols, which the bird collects as it passes through.

Super Bonus Symbols

If one of your three collected bonus symbols is a super bonus, you trigger the enhanced super bonus game instead. This is the CollectR collaboration entry, and you can tell they had a whiteboard session that got properly out of hand. Random activation when birds can no longer collect symbols. Birds leave field, symbols drop to fill spaces, then birds return to continue collecting.

Upgrade symbols increase gem levels by one, two, or three stages, never exceeding level seven. Each bonus symbol collected during free drops awards one additional free drop, so the feature can extend itself. Understanding responsible gambling practices becomes especially important when features can retrigger indefinitely. Line up the entrance and exit with collectable symbols and they’ll burrow through the station itself, snagging hidden feature symbols along the way. These innovations keep the game feeling lively and progression-based, especially during bonus rounds where upgrades and meter progress persist. One drop where the Alien Invasion feature triggers.

Rewards potential

Winning duels increases the Space Bandit spaceship multiplier. If a bonus game triggers during Alien Invasion, it’s automatically upgraded to super bonus.

Setting Your Bet

These show the numbers 1, 2, or 3 and upgrade one gem type by that many levels. If you collect an upgrade symbol showing 3, one of your four gem types jumps three levels up the payout ladder.

When multiple birds link through shared coins, their values sum for massive potential payouts. The expandable grid from 6×6 to 8×8 transforms gameplay dynamically. Corner bombs with randomised bird colours detonate when the matching bird lands on them, removing entire 3×3 areas and space station sections.

Transform Symbol

Black Hole appears as a black void with purple-blue glowing rings around it. When collected, it activates after birds can’t collect more symbols. The Black Hole absorbs everything on the grid – all symbols and birds – then throws them back in different positions. When birds are removed, all gems matching the removed bird’s colour transform into the colour of one or more returning birds. Progress on the grid size, collection meter, and gem upgrades persist throughout bonus rounds. Bombs can expand the grid further, while the black hole feature absorbs and redistributes symbols and birds randomly.

The Bonus Free Drops feature begins when a Bird collects 3 Bonus symbols during a given round. During this feature, the win level and reel area remain at the level they were at when the feature was triggered.

Triggered when a bird collects the red PRESS button symbol. The Space Bandit character appears and collects symbols column by column across the grid, activating features as encountered.

Four space station sections surround the main field, each holding up to 2 feature symbols. When corner bombs remove sections, they become tunnels. Birds pass through tunnels when collectible symbols exist at entrance and exit, collecting feature symbols inside.

If one of the three bonus symbols you collect is this variant, you trigger the enhanced super bonus game instead of the regular bonus. It detonates once the birds can no longer collect symbols, clearing a 3×3 area of the grid and removing part of the space station. This expands the grid — up to a maximum size of 8×8 — unlocking more symbols and boosting your win potential.

The birds then fly away horizontally, vertically, or diagonally. Corner bombs, Alien Invasion, Black Hole, coins, bonus symbols, and super bonus symbols aren’t removed or activated if they’re in the birds’ flight path. Gems are cleared along the flight paths but don’t count toward the symbol collection meter. The five X-iter modes offer distinct strategic approaches. Super Bonus at €500.00 guarantees maximum grid with all upgrades affecting all gems, optimal for maximum win hunting. Bonus Game at €100.00 provides standard bonus entry retaining main game progress.

Sugar Bomb 2 MultiBoost

You should expect extended periods without significant wins punctuated by occasional larger payouts. This volatility profile demands larger bankrolls relative to bet size to survive dry spells. A special MAX WIN coin symbol can land on the reels. When collected by a bird, this coin instantly pays whatever amount is required to reach the 10,000x cap. For example, if you’ve already won 3,500x your bet, the MAX WIN coin pays the remaining 6,500x to hit the cap. On mobile devices, the interface automatically adjusts to vertical orientation with touch-optimised controls.
