Slotsjudge's latest analysis of the Inner Fire Bonus Buy (updated) is based on extensive simulation, playing through 10,000 rounds daily with data refreshed regularly. The simulated RTP stands at approximately 80.99%, while the declared RTP is notably higher at 96.0%. The game exhibits a hit frequency of 19.6%, indicating that nearly one out of five spins produces a win, with an average return of around 4.13 times the wager. Its high volatility is reflected in the maximum win potential reaching up to 1852 times the bet, suggesting significant payout variance for players willing to endure the variance. The analysis emphasizes that real in-game conditions inform these results, providing a reliable glimpse into the game's performance, though the theoretical RTP surpasses the simulator's objective outcomes. Overall, the game presents a high-risk experience with the possibility of substantial wins amidst relatively frequent but lower-value payouts.

Inner Fire Bonus Buy is a high-volatility game with an RTP of 96.00%.

Inner Fire Bonus Buy has a very unbalanced paytable. For example, a 5-of-a-kind line of wilds is 80 times bigger than a 5-of-a-kind line for cherries. Fixed prizes also add unpredictability to the game. So, generally speaking, you cannot expect a balanced distribution of winnings from the slot.

The theoretical return to the player of Inner Fire Bonus Buy is 96.00%, which is a decent index for a modern slot.
