When you play the Cluster Tumble slot machine, you'll be drawn to its eerie and mysterious theme. The introduction is a newspaper headline, which describes a missing explorer and his wife's mission to find him. The slot's symbols include an animated heroine and a golden gargoyle that holds the matrix in place. A melodious tune accompanies the theme, which plays during the bonus games.
The game's wild symbol can act as any other symbol in the game, except for the scatter. When the lightning bolt appears, it transforms into a random symbol and pays out anywhere. Another feature is the Fire Transform block, which turns 1 to two symbols into the same type. After a win, the further wild symbol steps in, stepping in for all other symbols. Its life decreases with each winning cascade it forms.
If you've been playing the game on a desktop or laptop, you can also play Cluster Tumble online. You must first sign up for an account at a casino that uses Relax Gaming software. After logging in, you'll need to fill out a short application, including your personal information and payment details. Once you've submitted the information, you'll be able to play Cluster Tumble. Once you've done so, you can start playing.
The game is based on a unique 8-by-eight grid and combines blockers and cluster wins to create winning sequences. In addition to the free spins feature, clearing the blockade will award you with multipliers. You can win up to 20000X your bet. And the animation is quite decent. You'll probably get a few free spins when you match at least four of the game's symbols.
