Tower Run Treasure Steps follows Bob, a cheerful hero with a glowing sword, up a tower full of monsters and portals, with the Treasure Room waiting at the top.

The game is a 5x5 cascading grid with no paylines. Six or more matching Monster symbols, or seven or more matching Royal symbols, anywhere on the grid make a win. Winning symbols vanish and new ones fall in while wins keep forming. Wilds substitute for regular paying symbols.

Every win in a spin adds a charge to the Win-O-Meter of Destiny. At three charges, Wild Rift adds 1-4 Wilds. At six, Dimensional Multiplier adds more Wilds and a x2, x3, x4 or x5 multiplier for the next cascading sequence. At nine, the Treasure Room opens: a Hold & Spin round with three lives, sticky Coins worth x1-x5 the base bet and Mimic Chests hiding x10-x5000. On every spin Bob also walks 1-6 steps, and every 18 steps a Monster encounter pays x0.2 to x10 the base bet.

Play'n GO lists the RTP at 96.20%. Check the game's info screen at your casino before you play.
