If you have spent time with Fortune Gems 2 or Fortune Gems 3, the setup here will feel immediately familiar. The same 3×3 main grid, the same five fixed paylines, the same dedicated fourth reel running multipliers independently to the right. What changes with Fortune Gems 500 is what that fourth reel can do. Earlier entries topped their special reel at 15x. This one reaches 500x, and introduces the Ex NUDGE symbol, a grab mechanic that pulls multipliers downward repeatedly in a single spin and stacks the results. The series has been escalating its upside mechanism with each release, and this is the most aggressive version yet.
The fourth reel sits to the right of the main grid and spins on every round. Its centre position is the only one that counts. In standard play, eleven multiplier values can land there: 1x, 2x, 3x, 5x, 10x, 15x, 20x, 25x, 50x, 100x, and 500x. Whatever shows at the centre is applied to the total win for that spin. All winning payouts from the main reels are multiplied by this value before being paid.
The Ex NUDGE is the defining addition of this slot. It appears on the fourth reel only, and when it lands on a spin with a main reel win, the multiplier wheel activates. Instead of landing on a single multiplier, the wheel performs multiple downward grabs in sequence. The number of grabs is random and can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, or 50. Each grab pulls a multiplier value from the wheel. Those values are then added together and the combined total is applied to the spin’s win. A run of 10 grabs landing on 100x values each time would produce a 1,000x combined multiplier. A 50-grab sequence reaching high values consistently would push considerably further.
When the Ex NUDGE symbol lands, the grab count it carries is displayed on the symbol itself, so the number of pulls the wheel will perform is visible before the sequence begins.
The Ex NUDGE does not trigger on losing spins. A win on the main reels is required for the wheel to activate.
Fortune Gems 500 offers two Extra Bet tiers rather than the single tier in earlier series entries. Switching Extra Bet on opens a specification screen where one of two options can be selected before confirming.
The first option applies a 1.5x bet multiplier. In return, the 1x multiplier is removed from the special reel, leaving values from 2x upward, with improved distribution toward higher results.
The second option applies an 8x bet multiplier. This removes the 1x, 2x, 3x, and 5x values entirely, leaving the special reel with only 10x, 15x, 20x, 25x, 50x, 100x, and 500x. The probability weighting toward high-end multipliers increases significantly. At this tier, the base bet used for calculating winnings differs from the standard bet amount, so the effective cost is higher than a straight 8x of the standard stake. The in-game rules screen confirms the calculation method for each configuration.
Extra Bet can be disabled at any point by switching it back to off. The free play demo includes full access to both Extra Bet tiers.
Fortune Gems 500 runs a dynamic paytable, meaning the values displayed scale with the chosen stake rather than being fixed multipliers. Wins pay left to right on selected paylines. Only the highest win is paid on each payline, and wins on different paylines are added. The payout formula for standard play divides the base symbol payout by 5 before applying the special reel multiplier — the fifth payline acts as the denominator in the calculation rather than being a simple additive line. At the default illustration stake of 0.60, the top symbol pays 15 and the lowest pays 1.20 for three of a kind before the special reel is applied.
The Wild appears on all reels and substitutes for all other symbols. There are no scatter symbols and no free games round. The maximum payout in a single game is capped at 2,500,000, with a maximum multiplier of 12,500x.
RTP is reported at 97% by aggregators, though this is not currently confirmed on the official TaDa Gaming page. Volatility is listed as Low-Med on the official page. Check the in-game rules screen for the configuration active on your platform.
