And can award you between 1.5 and 25 x of your stake for 6 on a pay line. All winning symbols are removed through the Tumble mechanic, and new existing symbols drop down to fill the gaps. This process repeats as long as you keep winning, and you can get an indefinite extra win per spin. The game has an Expanding Wild feature that can be triggered both in the base game and during the bonus round. Each Tumble win increases the multiplier with an additional 1 and the multiplier resets to 1x between paid spins in the base game.
