What Is Space Invaders Win and Spin?
Space Invaders Win and Spin is an online slot game developed by Inspired, featuring 5 reels and 25 fixed paylines. The game uses a combination of themed symbols, bonus features, and jackpot mechanics to provide varied gameplay, all governed by the detailed rules and features below.
How Do the Paylines Work?
- The game is played with 25 fixed paylines.
- Winning combinations can occur on any or all of the paylines.
- Only the highest win for each combination is paid out on a given line.
- Winning combinations pay from the leftmost reel to the right across adjacent reels, except for Bonus wins.
- Wins from different paylines are added together.
What Is the Wild Symbol and How Does It Work?
- The Wild symbol substitutes for all other symbols except for the Win & Spin symbols.
- Wilds are found exclusively on reels 2, 3, 4, and 5 during the base game.
What Are Win & Spin Symbols?
- Win & Spin symbols appear both in the base game and during the Win & Spin bonus, and they can land on any of the five reels.
- There are two types: Invader Cash symbols, which display a cash value, and UFO Jackpot symbols, which display one of the Mini, Minor, or Major jackpots.
- Invader Cash symbols show values ranging from 1x to 9x the current stake.
- UFO Jackpot symbols pay out a Mini Jackpot (10x stake), Minor Jackpot (25x stake), or Major Jackpot (100x stake).
- Landing six or more Win & Spin symbols of any kind triggers the Win & Spin bonus feature.
- Win & Spin symbol values are only collected during the Win & Spin Bonus.
How Is the UFO Coin Trigger Activated?
- Each time a UFO Win & Spin symbol lands during the base game, a coin is added to a pile above the reels.
- The coin pile can increase up to five levels in visual size, though this does not influence the trigger rate or bonus values.
- After adding a coin, there is a chance the pile may drop and activate the Win & Spin Bonus.
- Adding multiple coins in a single spin increases the probability of triggering the bonus.
- If fewer than six Win & Spin symbols are present when triggered, extra symbols are added to ensure the bonus can begin.
- The odds of landing UFO Jackpot symbols in the bonus are higher when the feature is triggered by the coin pile.
How Does the Win & Spin Bonus Work?
- The bonus is activated by landing six or more Win & Spin symbols, or from the coin pile trigger.
- At the start, all visible Win & Spin symbols are locked in place.
- The bonus begins with three spins. Each time a new Win & Spin symbol appears in an empty position, it locks in place and the spins reset to three.
- The bonus round ends if either all fifteen positions are filled or there are no spins left.
- At the end of the round, all visible Win & Spin values are awarded.
- If every position on the reels is filled, the Grand Jackpot of 1000x the current stake is awarded in addition to other wins.
What Is the Cannon Feature in the Bonus?
- If no new Win & Spin symbols appear on the final spin, the cannon feature may be activated.
- Mini invader characters can appear in remaining empty positions and may be changed into Win & Spin symbols by the cannon.
- If, after this, all reel positions are not filled, spins are reset to three and the bonus continues.
What Are Fortune Spins?
- Fortune Spins is an alternative base game mode where only Win & Spin symbols land on the reels.
- This mode increases the chances of activating the Win & Spin Bonus feature.
- Fortune Spins can be played at any bet size between £0.10 and £5.00.
How Does Fortune Bet Work?
- Fortune Bet can be activated in either the standard spins or Fortune Spins modes.
- This sets the wager at 1.5 times the chosen stake.
- More UFO Win & Spin symbols are added to the reels, improving the likelihood of triggering the bonus through the coin pile.
- Win line and Win & Spin symbol awards are not increased by the Fortune Bet multiplier.
What Is the Gamble Feature?
- The Gamble feature may be available, or only offered when a win equals or exceeds five times the stake.
- If eligible, you may gamble your winnings using two wheels:
- The left wheel offers the chance to increase winnings by one third, double, or triple them.
- The right wheel gives a chance to trigger the Win & Spin Bonus (with 6, 7, or all 15 symbols), with higher tiers offering guaranteed UFO Jackpot symbols.
- A pointer landing on gold awards the prize shown; landing on silver results in the loss of winnings.
- The maximum potential payout from the Gamble feature is the lesser of 2500x stake or £50,000.
- The bonus wheel may award the Mega Win & Spin Bonus, where every position is filled with Win & Spin symbols.
- The RTP information is available within the game.
What Is Spin Chance?
- If your credits fall below the current bet amount but remain above zero, Spin Chance is triggered.
- This offers a chance to wager your remaining credits for an opportunity to win another spin.
- If the pointer lands on green, a spin is awarded; if it lands on red, your remaining credits are lost. The probability of winning is proportional to the remaining credits versus the required bet.
What Else Should I Know?
- The RTP is displayed within the game interface.
- All game outcomes are determined before play and are not influenced by player choices.
- A single game round cannot award more than £50,000 in cash winnings, not including jackpot payouts.
- The game can be recovered if play is interrupted.
- Any malfunction voids all pays and plays.
- Minimum bet per spin: £0.10. Maximum bet per spin: £5.00.
- Space Invaders Win and Spin has 5 reels and 25 paylines.
- Provider: Inspired.
