Space Invaders Win and Spin
The Space Invaders Win and Spin slot is set in a retro-inspired arcade universe, featuring the familiar pixel art style of classic video games. Iconic symbols like pixelated aliens, spaceships, and lasers spin across the reels, all set against a background that mirrors the starry depths of outer space. The game includes sounds and animations reminiscent of old-school arcade machines, creating a nostalgic atmosphere. Special features such as expanding reels and random spaceship appearances add to the familiar, light-hearted theme. The overall look and feel pay tribute to the beloved Space Invaders arcade game from the 1980s.
Game Summary
Space Invaders Win and Spin is an online slot developed by Inspired, featuring 5 reels and 25 fixed paylines. The game presents a selection of symbols, special features, and bonus rounds, operating under defined rules described in the following sections.
Payline Structure
- All spins are played with 25 fixed paylines.
- Winning combinations may appear on any or all paylines.
- Only the highest prize is awarded per winning combination.
- Winning combinations pay from left to right on adjacent reels, starting from the leftmost reel, except for Bonus wins.
- Prizes from different paylines are accumulated and paid together.
Wild Symbol Details
- The Wild symbol can substitute for all other symbols except Win & Spin symbols.
- Wilds appear exclusively on reels 2, 3, 4, and 5 during base game spins.
Win & Spin Symbols and Jackpots
- Win & Spin symbols can appear in both regular play and the Win & Spin bonus round, landing on any reel.
- Two types exist: Invader Cash symbols (which display a cash value) and UFO Jackpot symbols (displaying Mini, Minor, or Major jackpots).
- Invader Cash symbols feature values between 1x and 9x the current stake.
- UFO Jackpot symbols may award the Mini Jackpot (10x base bet), Minor Jackpot (25x base bet), or Major Jackpot (100x base bet).
- Landing 6 or more Win & Spin symbols of any variety triggers the Win & Spin bonus round.
- Win & Spin symbol values are paid only during the bonus round.
UFO Coin Pile Mechanic
- Every UFO Win & Spin symbol that lands in the base game contributes a coin to a pile displayed above the reels.
- The coin pile can grow to 5 distinct levels. Its size does not alter the chances of triggering the bonus or its payout.
- Once a coin is added, the pile may collapse, initiating the Win & Spin bonus round.
- Adding multiple coins in a spin increases the chance of activating the bonus feature.
- If fewer than 6 Win & Spin symbols are present at trigger, additional symbols are added before the bonus begins.
- Should the bonus be triggered by the coin pile, the likelihood of UFO symbols appearing is enhanced.
Win & Spin Bonus Round
- The bonus round is awarded either when 6 or more Win & Spin symbols land or when activated by the coin pile.
- All visible Win & Spin symbols at activation are locked in place.
- The feature begins with 3 spins. When new Win & Spin symbols land in empty positions, they are locked, and the spin counter resets to 3.
- The bonus ends once either all 15 positions on the reels are filled or no spins remain.
- At the conclusion of the bonus, all visible Win & Spin values are awarded.
- If every position on the reels is filled during the feature, the Grand Jackpot worth 1000x the base bet is granted, in addition to the collected wins.
Cannon Mechanic Within the Bonus
- If no new Win & Spin symbols appear on the last spin, the cannon feature may be triggered.
- Mini invaders will fill empty grid spaces, and the cannon may convert some into Win & Spin symbols.
- If, after the cannon action, the grid is not fully filled, the remaining spins reset to 3.
Fortune Spins Feature
- Fortune Spins is an alternative base game mode in which only Win & Spin symbols can land on the reels.
- This mode increases the chance of entering the Win & Spin bonus round.
- Fortune Spins can be played at any available stake.
Fortune Bet Option
- Fortune Bet may be activated for either standard spins or Fortune Spins.
- The bet multiplier is set to 1.5x the chosen stake.
- Additional UFO Win & Spin symbols are introduced to the reels, enhancing the chance of triggering the bonus via the coin pile.
- Payout values for win lines and Win & Spin symbols are not increased by the application of the bet multiplier.
Gamble Mechanic
- The Gamble feature may be available for any win, or for wins that are at least 5x the stake.
- If activated, players may gamble winnings on two wheels:
- The first wheel offers to increase winnings by one third, double, or triple them.
- The second wheel allows the chance to enter the Win & Spin bonus (with 6, 7, or all 15 symbols at the start), with guaranteed UFO symbols at higher levels.
- If the pointer lands on the gold segment, the corresponding prize is awarded. If it lands on silver, all winnings are lost.
- The maximum possible payout from a gamble is either 2500x the stake or £50,000, whichever is the lower amount.
- The bonus wheel can award the Mega Win & Spin Bonus, in which all positions are Win & Spin symbols.
- Return to player information is displayed within the game.
Spin Chance Mechanism
- If available funds drop below the current bet but are above zero, Spin Chance activates automatically.
- Spin Chance offers the opportunity to wager the last remaining credits for an additional spin.
- Success is determined by the pointer landing on green, with the likelihood based on the proportion of credits relative to the bet.
- If the pointer lands on red, the remaining credits are forfeited.
General Information

- All game results are pre-determined and unaffected by any choices during play.
