The heart, diamond, club and spade symbols form the group of low value symbols in Mega Cash Stacks that provide the player between x0.10 and x2 the original bet, depending on the number of matching symbols that land in a single spin. 

Up next is the medium value symbols, which consist of the currency emblems for Euro, British Pound, US Dollar and Chinese Renminbi. The provide the player between x0.80 and x4 the stake placed. 

The highest value regular symbol is the Mega Cash Stack. This offers players x1 for a three-of-a-kind win and x20 for a winning combination of five matching symbols. 

In addition, the game comes with a wild symbol, which substitutes for all symbols except the bonus. 


Mega Cash Stake includes a progressive free spins feature that is triggered by landing three or more bonus symbols in the base game during a solo spin. At the start of this round, the player is asked to spin a wheel to determine the amount of spins to be played – which can range between five and 15 spins. 

During this mode, the spin is always guaranteed to be greater than the last and it is concluded once the last progressiver free spin has been played.

The progressive free spins feature can be retriggered randomly by activating the five letters E X T R A under the reels. If a retrigger is awarded the progressive free spins metre is incremented by five spins. Only one retrigger can be awarded during a progressive spin feature.

Moreover, the title includes a Golden Bet – which increases the stake by 50 per cent to double the chance of activating the bonus and a Gamble mode.
