Bigger Bonanza Platinum Rush Express
About this game
A 5-reel, 4-row video slot machine.
The aim of the game is to spin the drums so that the symbols form different combinations.
Winning combinations are highlighted on the reels and a payout is awarded.
Betting rules
Each spin costs a total bet amount.
The total bet is based on the initial bet made, multiplied by the cost of the paylines played.
The initial bet is the current total bet multiplied by the cost of the payline, which is 20.
Payment line rules
This game includes 20 paylines.
The number of paylines played is fixed.
A payline is a pattern of adjacent symbol positions that spans a line across the reels.
A win is awarded when adjacent matching symbols appear on a payline.
Payline wins are formed from left to right, starting with the first reel.
Awards Rules
Payline winnings are based on the initial bet placed.
The value of the prize depends on the winning combination that is formed.
The total prize is the sum of all payline winnings from one spin.
If multiple winning combinations appear on a single payline, only the highest win is paid.
Only the highest winning combination of symbols is paid out.
The payout table shows the payout for each combination of symbols according to the current bet.

Rush Express™ Function
The bell, golden train, and platinum train symbols only appear on drum 5.
When a bell, golden train or platinum train symbol appears on reel 5 and at least one Rush Express™ symbol appears in the same spin, the Rush Express™ feature is activated.
When a bell symbol appears, you win all the Rush Express™ symbol prizes on the screen.
When a golden train or platinum train symbol appears, all Rush Express™ symbol prizes displayed on the screen are collected on the golden train or platinum train, respectively, above the reels. The golden train or platinum train awards between 3 and 15 times this total to the player.
The Rush Express™ symbols only appear on reels 1, 2, 3 and 4.
When a Rush Express™ feature is activated, all Rush Express™ train symbols award a mini train feature to determine the total prize value.
The color of the train received in the mini-function corresponds to the color of the Rush Express™ train symbol that is activated.
Each colored train car collects a cash prize or jackpot that activates the Rush Express™ train symbol.
The last colored train car can award a cash prize, a x2 or x3 multiplier, or the corresponding colored jackpot.
Free spins
When one or more gem symbols appear, there is a chance to activate 10 free spins.
The combination of gem symbols collected when the free spins are activated determines the upgrades awarded.
A symbol with two gems is collected in both minecarts of the same color above the drums.
It cannot be reactivated.
The Rush Express™ feature appears more frequently during free spins.
All bets and lines played are the same as those of the spin that activated the function.
The animation does not affect the activation of the function.
Green gem upgrade
When the green gem upgrade is active, a bell, golden train, or platinum train symbol is guaranteed to appear on every free spin.
Purple Gem Upgrade
When the purple gem upgrade is active, all bell symbols are upgraded and become gold train or platinum train symbols.
Pink Gem Upgrade
When the pink gem upgrade is active, the x2, x3 and x5 diamond multiplier symbols are added to the free spin reels.
The diamond multiplier symbols only appear on reels 1, 2, 3 and 4.
Diamond multipliers have a random multiplier of x2, x3, or x5.
Diamond multipliers are applied to the total of all prizes on screen when a Rush Express™ feature is activated.
Red gem upgrade
A second set of the free spins feature is awarded.
Each function set acts independently of the other set.
Cyan Gem Upgrade
When the cyan gem upgrade is active, additional x2, x3, and x5 gold nugget symbols are added to the free spins reels.
Selection function
At the end of each spin of the base game, the nugget symbols may randomly trigger the Selection feature.
Match 3 identical icons to win the corresponding jackpot: MINI, MINOR, MAJOR or GRAND.
The selection function can only be activated after a roll of the base game that did not result in a Rush Express™ function.
The selection function cannot be activated from free spins.
The animation does not affect the activation of the function.
Wildcard symbols
The symbols in Bigger Bonanza Platinum act as wild cards.
Wild symbols can create their own winning combination when they appear in a payline combination.
Wild symbols can substitute for all symbols except gem symbols, Rush Express™ symbols, diamond multipliers, bell symbols, gold train symbols, and platinum train symbols.
Wild symbols accumulate on all reels and only appear in the base game and free spins.
