How to Win

When you first open Space Stacks, you’ll notice that it has a very unusual format:

  • The betting options pop-up over top a 10x10 grid.
  • You can place chips worth .01 coins to £1 coins on different tiles which represent the different tiles. In this sense, it’s a lot like roulette.
  • You place your chips on the different tiles to make a wager. You can bet on as many tiles as you want.

The round begins when you hit the spin button at the bottom of the screen. First, a random multiplier is chosen, increasing the value of any of the number-based columns.

Then, over a series of spins, symbols will drop into each of the columns. If a full column is filled, you’ll win the prize that has been assigned to that column.

If you fully fill the 7th, 8th or 9th columns, you’ll trigger one of the bonus rounds. Filling the MAX column will provide you with the top win of 5000x.

You can trigger multiple prizes at once, and the maximum prize available is 5000x from these blocks.
