During the spin the symbols fall from the top.

The Wild symbol substitutes all the symbols except Scatter and Game.

The winning symbols of each spin ‘fly away’, while the others are “sticky” for a new Free Spin (respin) in which new symbols fall down to replace the previous winning ones.

The game has incremental multipliers. Each winning spin increases the multiplier for the next spin. The sequence of the multipliers is x1, x2, x3, x5. A losing spin restarts the multiplier at x1.

Three Game symbols activate the Bonus Game during which the player opens the boxes until the empty one is found.  The total winnings are the combined sum of the value of each box chosen until the empty one is found.
