Whenever you achieve a winning combination, all contributing regular paying symbols - plus any matching types visible on the reels - will vanish to make way for a new set tumbling down into the vacant cells - leading to potentially lengthy cascade snowballs.

The process repeats as long as wins continue to form with each subsequent cascade.

Watch as every position forming part of a win is highlighted with a Golden Square once that symbol disappears from the reels. All Golden Squares are then activated should a Rainbow be present on the same spin - prompting affected positions to receive coin values from Bronze to Gold, or one of two special symbols: Four-Leaf Clovers and Pots of Gold.

Bronze Coin multiplier values range from 0.2x to 4x, while Silver Coins offer values worth between 5 and 20x  and Gold Coins bring values worth up to 500x.

Once all Coin values are revealed, any Four-Leaf Clovers on show multiply their adjacent cells (including Pots of Gold symbols) by values from 2x to 10x.

Next, any Pot of Gold symbols on the reels come into play - collecting the aggregated values of Coins in view plus other Pots of Gold, before storing the total multiplier sum. Pots of Gold activate in an order of top-to-bottom, left-to-right.

It's also possible to land more than one Pot of Gold symbol in a spin, which collect each other's value following Coin collections. After the last Pot of Gold in view is done collecting, Golden Squares get re-activated for one more round and the process repeats.

Triggered organically by landing 3 FS base game symbols, benefit from Golden Squares remaining highlighted between spins until they're activated by a Rainbow.

Retriggers are a possibility, where 2 FS symbols get you an extra 2 spins and 3 FS symbols grant 3 more.

What's more, you can upgrade instantly to the ALL THAT GLITTERS IS GOLD round by landing 4 FS symbols. This sees you carry your current free spins haul plus an additional four spins into the next feature.

Beginning with 12 free spins, this bonus is triggered by 4 FS symbols landing at once in the base game. Here, all Golden Squares remain highlighted throughout the entire bonus round and can be activated again, and again (and again)! Look out for the all-important Rainbow symbol dropping to capitalize on all those Golden Squares.

Re-triggers can be earned in the same manner as the previous bonus round.

Saving the best for last, land 5 FS symbols during a base game spin to enter Le Bandit's holy grail with 12 free spins.

What's so special about TREASURE AT THE END OF THE RAINBOW? All highlighted squares remain illuminated throughout, while a Rainbow feature is guaranteed to land on EVERY SINGLE SPIN - spelling bumper rewards.

Trigger this bonus (which cannot be purchased) and begin to smell the tantalizing treasures awaiting at the rainbow's end.
