What to expect from the slot is easier to understand by examining the test in detail:

  1. First 100 spins - loss of approximately 86 bets (!). No payouts larger than 10 bets.
  2. Next 200 rounds - continued fall. 280 bets were lost around the 340th spin. During this period, there were only two normal payouts — x12 and x16.
  3. The spins of the 4th hundred gave four good payouts with an interval of 15-20 rounds: x48, x24, x17 and x144. Последнюю, самую крупную, принес стековый символ замены (Wild) с множителем x12.
  4. 505th and 512th spins pay x64 and x100. Lose about 300 bets completely eliminated. A small plus has appeared.
  5. On the 522nd spin a bonus appears. It is triggered by 3 Bonus symbols. The player chose the option with 10 free spins and the “Stack substitute” feature.
  6. Progress of the bonus game: for the first 8 free spins, the winnings amounted to +2 bets (?!). On 9- m dropped the expected stack substitute. It generated over 25 respins, during which a second stacking wild appeared. During repeated spins, the multipliers of both special symbols grew. The final coefficient is x78. Bonus win - 336 bets.
  7. Regular spins from 550th to 1000th were mediocre. There was one x50 payout. But at the same time, the +350 profit formed after exiting the bonus game was not completely lost. The session ended with +240 bets.

Comment: You can't count on special features in the main game (see below). "Mysterious" wildcards did not bring profit. The stack substitute appeared no more than 10 times, not guaranteeing a win in the round. And additional bonus symbols that activate scatter payouts never landed.

Expert Tips

The Iron Bank (Relax Gaming) slot machine is extreme. It is suitable for experienced players with strong nerves and a bankroll of 1000 bets. The potential of the slot is huge - +500-1000 bets in 100 rounds. These short "fertile" periods alternate with longer periods of balance and complete "drought".

Beginners are advised not to get involved in long sessions. It is better to play in short runs of 10 rounds, closing the slot with any result.

An alternative strategy if you have a serious bankroll is to use only the purchase of the bonus. This approach requires testing all three free spin options - at least 20 spins for each.

The Iron Bank slot is available in almost any online casino that accepts users from Russia. High volatility is not suitable for bonus wagering.
