Gameplay

Game Layout

The game is played on a 5×4 Reel with a Slingo Grid above.

The Grid contains randomly selected numbers from 1-75, with up to 15 numbers available in each of the 5 columns.

The Grid and 5×4 Reel contain aliens and numbers.

A separate set of Grid numbers is generated for each stake level.

These persist for the duration of the game at that stake until Cosmic Spins are activated.

After a Cosmic Spins round, a new Grid is displayed for the selected stake level.

How to Play

Select your stake and press SPIN to play.

Aliens and numbers spin into the 5×4 Reel.

4+ aliens form a Cluster and pay according to the paytable.

Numbers matched in the same column on the Reel and Grid will be replaced by aliens.

Completed clusters of aliens explode and more symbols spin in.

The spin continues until no wins appear.

Number Match

A number match is when any number on the Reels matches a number in the Grid in the corresponding column above.

The matched numbers will highlight.

The matched numbers will then disappear and an alien will spawn on the reels and move on to the Grid.

All 7 aliens can be spawned via number match.

Revealing 4+ matching aliens on the 5×4 Reel forms a Cluster which pays the corresponding prize in the Pay Table.

Aliens are matched only if directly above, below, or to the left or right of another matching symbol.

Aliens pay the same in both base game and Cosmic Spins.

All awards are a multiplier of selected game stake.

Slingo Lines

A Slingo is a completed line on the 5×5 Slingo Grid.

Slingos are created by having a line of 5 Aliens (dabs) on the Grid.

Up to 12 Slingos are available.

More than one Slingo can be awarded in a single spin.

12 Slingos is also called a Full House.

Each Slingo will award one or more Cosmic Spins.

The order of the Slingos achieved does not affect these awards.

Slingo Awards

Players start the game with 1 Cosmic Spin.

The number of current Cosmic Spins is shown in the Cosmic Spins counter.

A maximum of 25 Cosmic Spins can be awarded.

Cosmic Spins

Cosmic Spins Trigger

Cosmic Spins are triggered by completing a Cluster of 4+ matching aliens on the Slingo Grid OR achieving a Full House.

Any unmatched numbers in the Slingo Grid become Frozen positions.

Frozen positions prevent an alien from joining a cluster.

Aliens can still cascade through Frozen positions.

The Slingo Grid attaches to the 5×4 Reel underneath to become a single 5×9 Cosmic Spins Reel.

Cosmic Spins Rules

Slingos award up to 25 Cosmic Spins.

All Cosmic Spins will be played out on the 5×9 Free Spins Reel.

Frozen positions remain frozen throughout Cosmic Spins.

All aliens can cluster and cascade as with the Base game.
