About This Game

Navigate this 6-reel, 5-row game with cluster wins, cascades and the Tenta-Grab mechanic.

Features

Wild Symbols And Wild Multiplier Symbols

The Wild symbol substitutes for all symbols in the paytable.

Wild symbols can also land with one of the following adding multiplier values: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x.

Ink Stains

When there is a win on the grid the win will be calculated, the winning symbols will be removed and new symbols will drop in to replace them. The winning positions will be marked with Ink Stains. Ink Stains are removed from the grid after they have been used by the Tenta-Grab mechanic, and they are reset between spins.

Eye Of Otto And The Tenta-Grab Mechanic

The Eye of Otto symbol activates the Tenta-Grab mechanic when it lands on a grid with Ink Stains. When activated, the Tenta-Grab mechanic will randomly grab one symbol on the grid, and replace all Ink Stained positions and itself with the grabbed symbol. The Tenta-Grab mechanic can grab low symbols, high symbols, FS symbols, Wild symbols or Wild Multiplier symbols.

If a Wild symbol or a Wild Multiplier is grabbed by the Tenta-Grab mechanic, the replacing symbols will be either Wild or Wild Multipliers with higher or lower values than the chosen symbol.
