Game Summary

Space Invaders Win and Spin is a slot machine with 25 fixed paylines developed by Inspired. It features a range of symbols and special bonus mechanics, each described in detail below.

Game Structure and Paylines

This slot is played on a set of 5 reels.
There are always 25 fixed win lines in play.
Winning combinations are paid on the highest value per evaluated line.
Payouts are awarded for matching symbols from left to right on consecutive reels, beginning with the leftmost reel, except for Bonus wins.
Wins on separate paylines are totalled together.

Betting Range

The minimum bet per spin is £0.10.
The maximum bet per spin is £5.00.

Wild Symbol Mechanics

The Wild symbol substitutes for all standard symbols, except for Win & Spin symbols.
Wild symbols appear only on reels 2, 3, 4, and 5 during base game spins.

Win & Spin Symbols and Features

Win & Spin symbols may appear on all reels during both the base game and within the bonus.
These symbols include Invader Cash symbols, which display cash values, and UFO Jackpot symbols, which display Mini, Minor, or Major jackpots.
Invader Cash symbols can show a value from 1x to 9x the current stake.
UFO symbols correspond to fixed jackpot values: Mini Jackpot is worth 10x the base bet, Minor Jackpot awards 25x the base bet, and Major Jackpot awards 100x the base bet.
Landing 6 or more Win & Spin symbols in any spin activates the Win & Spin Bonus feature.
Values on Win & Spin symbols are only paid during the Bonus round.

UFO Coin Feature

Each time a UFO Win & Spin symbol lands in the base game, a coin is added to a coin pile displayed above the reels.
The coin pile can reach up to five levels in height. The pile’s size does not influence trigger probability or total bonus value.
After a coin is added, there is a chance that the pile will fall and trigger the Win & Spin Bonus.
Landing multiple UFO Win & Spin symbols in a single spin may further increase the chance of triggering the bonus.
If the bonus is triggered with fewer than 6 Win & Spin symbols on the reels, extra symbols are automatically added before the bonus begins.
When the Win & Spin Bonus is activated by the coin pile, the likelihood of seeing UFO symbols during the bonus round is increased.

Win & Spin Bonus Round

This bonus triggers when 6 or more Win & Spin symbols appear in a spin, or when activated by the coin pile.
At the start of the bonus, all currently visible Win & Spin symbols are locked in place.
The feature begins with three spins. Each time a new Win & Spin symbol lands in an empty position, it locks in place and the spin count resets to three.
The round continues until all 15 positions (the entire grid) are filled with Win & Spin symbols, or when no spins remain.
At the end of the bonus, all Win & Spin symbol values displayed are collected and awarded.
If all 15 positions are filled, an additional Grand Jackpot of 1000x the base bet is awarded, alongside other winnings accumulated in the round.

Cannon Feature During Bonus

If no new Win & Spin symbols land on the final spin of the bonus, the cannon feature may be activated.
Mini invaders appear in the remaining empty positions and may be converted to Win & Spin symbols by the cannon mechanism.
If, after this sequence, fewer than 15 positions are filled, the spins reset to three and the bonus continues.

Fortune Spins Mode

Fortune Spins is an alternate base game mode, where only Win & Spin symbols can appear on the reels.
This mode increases the probability of entering the Win & Spin bonus.
Fortune Spins is available at any selected stake within the game’s betting range.

Fortune Bet

Fortune Bet can be activated in both standard and Fortune Spins modes.
Activating Fortune Bet sets the wager to 1.5 times the selected stake.
This feature adds extra UFO Win & Spin symbols to the reels, enhancing the opportunity to trigger the bonus through the coin pile.
Payouts for win lines and Win & Spin symbols are not increased as a result of the bet multiplier.

Gamble Feature

The Gamble Feature may be offered for any win, or only for wins equal to or greater than 5x the stake, depending on game settings.
When eligible, a gamble option is presented with two wheels:
- The left wheel allows players to potentially increase their winnings by one third, double them, or triple them.
- The right wheel provides chances to win the Win & Spin bonus, with 6, 7, or all 15 bonus symbols awarded, and higher tiers guarantee UFO symbols.
If the pointer on a wheel lands on a gold segment, the associated reward is granted; landing on a silver segment results in all winnings being lost.
The maximum possible payout from a single gamble is the lower of x2500 stake or £50,000.
The bonus wheel may award up to the Mega Win & Spin Bonus, which fills all symbol positions with Win & Spin symbols.
The game shows the RTP information in-game.

Spin Chance Feature

If a player's credits fall below the current bet, but remain above zero, the Spin Chance feature is triggered automatically.
This offers a chance to wager remaining credits to win an additional spin.
A wheel with green and red segments determines success; the chance of a win is proportional to the ratio of credits to the selected bet.
If the pointer lands on green, another spin is awarded. Landing on red results in the loss of the remaining credits.
