Discover Space Invaders Win and Spin Slot
Space Invaders Win and Spin is a slot experience developed by Inspired, featuring 25 fixed paylines across 5 reels. The game includes a variety of themed symbols, special features, and bonus rounds, all explored below.
Paylines and Winning Combinations
- This slot always plays with 25 fixed paylines.
- Winning combinations can appear on any or all paylines during a spin.
- Only the highest win for each winning symbol combination is granted per line.
- Wins pay from left to right across adjacent reels, starting from the first reel to the left, except for bonus wins.
- Wins on different paylines are added together to form the total win for the spin.
Wild Symbol Details
- The Wild symbol can substitute for any other symbol except for Win & Spin symbols.
- Wilds are present on reels 2, 3, 4, and 5 during standard base game spins.
Understanding Win & Spin Symbols
- Win & Spin symbols can appear on any reel in both the base game and the bonus round.
- There are two types: Invader Cash symbols, displaying a cash value, and UFO Jackpot symbols, showing Mini, Minor, or Major jackpots.
- Invader Cash symbols can range from 1x to 9x your active stake.
- UFO Jackpot symbols award set prizes: 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 kind will activate the Win & Spin bonus round.
- Payouts from Win & Spin symbols are only granted during the Win & Spin Bonus.
UFO Coin Feature
- When a UFO Win & Spin symbol appears in the base game, a coin is added to a pile above the reels.
- The coin pile can grow up to 5 levels, but size does not affect trigger chances or bonus values.
- After a coin is added, the pile may fall and randomly trigger the Win & Spin Bonus.
- Adding multiple coins in a single spin increases the chance of triggering the bonus.
- If there are fewer than 6 Win & Spin symbols present when the coin pile triggers the bonus, extra symbols are added before the bonus starts.
- The likelihood of UFO symbols appearing in the bonus increases when triggered by the coin pile.
Win & Spin Bonus Round
- This bonus is activated by landing 6 or more Win & Spin symbols or through the coin pile feature.
- At the start of the bonus, all Win & Spin symbols on the reels become locked.
- The bonus gives 3 spins. Every time one or more new Win & Spin symbols appear in empty positions, they are locked and your spin count resets to 3.
- The feature concludes when either the grid is completely filled (15 positions) or no spins remain.
- When the bonus ends, all displayed Win & Spin values are awarded.
- Filling all 15 positions in the bonus also awards the Grand Jackpot, worth 1000x the base bet, in addition to other collected wins.
The Cannon Feature in the Bonus
- If no new Win & Spin symbols appear during the final bonus spin, a cannon may be triggered.
- Mini invaders may appear in remaining empty spaces, which can be transformed into Win & Spin symbols by the cannon.
- If all 15 positions are not filled after this sequence, spins are reset back to 3.
Fortune Spins Mode
- An optional base game mode in which only Win & Spin symbols land on the reels.
- Playing in Fortune Spins increases the likelihood of entering the Win & Spin bonus.
- Fortune Spins are available at any stake between £0.10 and £5.00.
Fortune Bet Option
- Can be activated in regular play or during Fortune Spins.
- Sets the bet multiplier to 1.5 times your current stake.
- Adds more UFO Win & Spin symbols to the reels, boosting the chance of triggering the bonus via the coin pile.
- The payout values for win lines and Win & Spin symbols are not increased by this bet multiplier.
The Gamble Feature
- This feature may be enabled, or enabled only for wins of at least 5x the stake.
- When eligible, you may gamble your win using two wheels:
- The left wheel offers the chance to increase winnings by one third, double or triple them.
- The right wheel gives an opportunity to win the Win & Spin Bonus with 6, 7, or all 15 symbols, with higher-tier awards including guaranteed UFO symbols.
- Landing the pointer on gold brings the reward, while landing on silver forfeits all winnings.
- The most that can be won via the Gamble Feature is either 2500x your stake or £50,000, whichever is lower.
- The bonus wheel may grant the Mega Win & Spin Bonus, filling every position with a Win & Spin symbol.
- Information about return to player is shown in the game.
Spin Chance
- This feature automatically activates if your credits fall below the chosen bet, but are still above zero.
- It lets you wager your remaining credits for a chance at another paid spin.
- If the pointer lands on green, you are awarded a spin; red means the remaining credits are lost.
- The probability of winning is directly proportional to your remaining credits versus the current bet.
Additional Information
- Return to player details are available within the game.
- Results on the slot are pre-determined and player choices do not influence odds or outcomes.
- The most that can be won in a single game, excluding jackpots, is £50,000.
- If interrupted, the game will recover your session.
- Any malfunction nullifies all pays and plays.
