Basic Rules

The base game is played on a 5×3 grid, with 25 lines.

All line wins pay from left to right on adjacent reels, starting with the leftmost reel.

Only the highest win is paid per winning combination.

Wins on multiple lines are added together.

Special reels are in play during the bonus game.

All wins are shown in currency.

Malfunction voids all pays and plays.

Wild

Wild substitutes for all symbols except Cash symbols.

Appears on all reels and can be stacked.

Cash Symbols

Cash symbols are visually represented differently in base and bonus games.

Each cash symbol has a prize displayed on it.

Base game cash symbols can appear anywhere on reels during the base game.

Bonus game cash symbols appear only in bonus features. The upgraded version appears only in Coin Boost.

Cash symbol values are only paid in the bonus game.

Prizes displayed during base game and bonus game are:

x0.5, x1, x2, x3, x4, x5, x8, x10, x12, x20, x25, x30, x35, x50, x15 (Mini), x40 (Minor), x200 (Major) bet.

Bonus Game

Cash symbols in the base game are green, red, or blue and correspond to green, red, and blue tiki heads.

Landing a cash symbol in the base game can randomly trigger the corresponding bonus feature.

It is possible to trigger one feature, a combination of two, or even all three features.

The filling of tiki heads is random and unrelated to the player’s bet value.

All bonus game features are based on Hold and Respin.

At the start of any bonus game, all base game cash symbols (girls) that landed in the triggering spin will turn into bonus game cash symbols (orbs) with the same prize displayed and stay locked until the end of the bonus game.

During the bonus game, all cells spin as individual reels and only cash symbols may appear.

Each new cash symbol that lands stays locked until the end of the bonus game and resets the respins back to its original starting value.

If no new symbols land, the remaining respins decrease by 1.

The bonus game ends when no more respins are left or when there are no more empty cells.

When respins end, the sum of all cash prizes on the screen is awarded.

Filling all the positions awards an additional prize of x1000 (Grand) bet.

Initial respins awarded may vary based on the feature combination.

Coin Boost

Whenever a green base game cash symbol lands, there is a chance to trigger the Coin Boost feature.

In this feature, 3 initial respins are awarded.

In this feature, cash symbols can randomly be increased during each spin by: x2, x3, x5, x10, x15, x20, x25, x30, x40, x50, x60, x75, x100 bet.

Symbols with Mini, Minor, or Major prizes cannot be increased.

Upgraded cash symbols are visually represented by a brighter orb.

Mighty Reel

Whenever a red base game cash symbol lands, there is a chance to trigger the Mighty Reel feature.

In this feature, two 5×3 reel matrices are awarded with 3 initial respins each.

An additional reel is added at the beginning of the bonus game.

Cash symbols are copied to the corresponding positions on the additional reel matrix.

After that, both reel matrices behave independently during the feature.

Extra Spins

Whenever a blue base game cash symbol lands, there is a chance to trigger the Extra Spins feature.

In this feature, 4 initial respins are awarded.

Every time an additional bonus game cash symbol lands, the number of respins is reset to 4.
