Does the Slingo Space Invaders Game Pay Real Money?

How To Play the Slingo Space Invaders Game 

A round hands you 12 spins and a single grid of 25 numbers to work through.

  1. Set your stake: Choose a wager from $0.20 to $20 using the stacked coins icon.
  2. Take your spin: Tap the “Spin” button to fill the five reel positions beneath the grid.
  3. Mark your numbers: Any reel number that matches a number in the column above it is marked on the grid.
  4. Complete your lines: Every full line of five marked numbers is a Slingo, and each one moves you up the Payladder.
  5. Watch the skies: When a Cannon lands, it fires a Beam up its column at any UFO positioned above it.

Slingo Space Invaders Game Features

This game runs two layers at once. Matching numbers helps you complete Slingos and move up the Payladder, where Cash awards, Bonus Lives, and Bonus Game multipliers come into play. 

Slingo Space Invaders Wild Feature

The Wild is a red tile with an upward chevron. When one lands, you can mark any number in the column directly above it, helping you move closer to completing a Slingo. 

Slingo Space Invaders Super Wild Feature

The Super Wild is the gold version, and unlike a regular Wild, it lets you mark any number anywhere on the 5×5 grid. That gives you more freedom to choose a position that moves you closer to completing a Slingo. 

Slingo Space Invaders Cannon Feature

Cannons are the green turrets on the reel, and they’re what turns a number grid into a shooting gallery. When one lands, it fires a beam straight up its own column, and any UFO drifting above that column is destroyed. If nothing happens to be flying over it, the shot simply misses.

Slingo Space Invaders UFO Feature

There are two types of UFOs that can appear, each offering different rewards.

Slingo Space Invaders Gold UFO Feature

Gold UFOs start appearing once you’ve completed your first Slingo, and each one carries a visible cash value. Destroy it and that value drops straight into the Cash Pot. What it’s worth depends on how far you’ve climbed: between one and three Slingos it pays 1x your stake, and from four Slingos onward it can pay 1x, 3x, or 5x.

Slingo Space Invaders Red UFO Feature

Red UFOs don’t appear until you’ve completed four Slingos. Instead of awarding Cash when destroyed, each one adds a Bonus Life to the Bonus Life Meter for use in the Bonus Game. You can collect up to three Bonus Lives from Red UFOs during the Base Game, and Red UFOs don’t appear above the Slingo Grid during Extra Spins. 

Slingo Space Invaders Payladder Feature

The Payladder runs up the left of the screen and displays Cash awards, Bonus Lives, and Bonus Game multipliers as you complete Slingos. There are 12 Slingo win lines but only 11 Payladder awards because completing the final number on the grid always awards at least two Slingo lines. 

Slingo Space Invaders Bonus Game Feature

The Space Invaders Bonus Game features moving Invaders on a new game screen. Invaders enter from the top left and move between one and five steps per spin along a set path toward the bottom right. Cannons on the Bonus Reel fire at Invaders above them, with successful hits adding Cash to the Bonus Pot.

If an Invader reaches the end of the path without being hit, you lose a Bonus Life and any other Invaders on the bottom row are removed. The Bonus Game ends once all of your Bonus Lives are lost.

Slingo Space Invaders Bonus Cannon Feature

The Bonus Reel can land Single, Double, and Triple Cannon symbols. A Single Cannon fires one Beam, a Double Cannon fires two, and a Triple Cannon fires three. Cannons fire from left to right, and after a Double or Triple Cannon lands, the reel won’t spin again until all of its Beams have fired. Blank positions don’t fire a Beam. 

Slingo Space Invaders Bunkers Feature

Bunkers are red barriers that can appear above the reels. They absorb Cannon shots that would otherwise travel upward, and each Bunker is destroyed after three hits. 

Slingo Space Invaders Bonus Lives Feature

You can carry up to eight Bonus Lives into the round, with a maximum of five earned from the Payladder and up to three from shooting Red UFOs. Your total isn’t locked once the round begins, though. Red UFOs appear in the bonus too, and shooting them tops up the same meter.

Slingo Space Invaders Extra Spins Feature

After the initial 12 spins, Extra Spins can be purchased to continue the game. The price of each Extra Spin depends on the current grid position and potential prizes, so it can be higher than your original stake. The next price appears on the “SPIN FOR” button. 

Play Controls also let you set limits for the number and price of Extra Spins offered, as well as the total stake and total loss for a single game. 

Slingo Space Invaders Game Bonuses and Jackpots

This Slingo arcade game features additional cash awards from Gold UFOs and Invaders collected during the Space Invaders Bonus Game.

Gold UFOs award Cash when they’re destroyed. In the Base Game, they award 1x the selected stake after one to three Slingos and 1x, 3x, or 5x from four Slingos onward. In the Bonus Game, Gold UFOs award 2x, 6x, or 10x the selected stake.

Invaders have separate values in the Bonus Game: the Octopus awards 0.1x, the Crab 0.2x, and the Squid 0.4x the selected stake. These Invader values are then multiplied by the applicable Bonus Game multiplier, which ranges from 1x to 50x, before being added to the Bonus Pot.

How To Win the Slingo Space Invaders Game

Wins come from marking numbers rather than lining up symbols on a payline. Every complete line of five marked numbers is a Slingo, and completing Slingos moves you up the Payladder toward its Cash awards, Bonus Lives, and Bonus Game multipliers. Cash awards start at 0.2x the selected stake for three Slingos and increase through the available Payladder awards, reaching 40x when the full grid is completed. Wilds can mark a number in the column above them, while Super Wilds can mark a number anywhere on the grid. 

Away from the Payladder, destroyed Gold UFOs award Cash, while Invaders collected in the Bonus Game have stake-based values that are increased by the applicable Bonus Game multiplier. 

Setting limits and managing your bankroll before you start can help keep your play within budget. 

Slingo Space Invaders Game Graphics and Design

Like other retro-styled online video arcade games, this one leans into its 1980s arcade roots. The grid floats over a deep navy starfield, framed by snow-capped purple mountains and burnt orange terrain, with a white and red rocket along the left edge beside the Payladder. Pixel-style Invaders appear in neon pink, blue, and green, while the Cannons glow bright green, which fans of the earlier games are bound to appreciate. A dark monster silhouette fills the lower-right corner of the board, adding a reminder of the dangerous threat to humanity that must be stopped. Modern arcade-style sound effects carry the retro theme into the audio. 

Slingo Space Invaders Game Symbols

The reel below the grid carries numbers plus three special symbols. The Wild is a red tile with an upward-pointing arrow, the Super Wild is a gold version, and the Cannon is a bright green turret. Wilds and Super Wilds help you mark grid numbers, while Cannons fire at UFOs positioned above their reel column.

Other prize values appear around the game. Payladder Cash coin awards begin at 0.2x the selected stake for three Slingos and can reach 40x for completing the grid. Gold UFOs award 1x the stake with one to three Slingos and 1x, 3x, or 5x from four Slingos onward in the Base Game, while Bonus Game Gold UFOs award 2x, 6x, or 10x. In the Bonus Game, the pink Octopus is worth 0.1x, the blue Crab 0.2x, and the green Squid 0.4x before the applicable Bonus Game multiplier is applied to the collected Invader value.
