3 Apex Treasures (Iron Dog Studio) — slot review for players from United Kingdom

How the Bonus Works in 3 Apex Treasures

The main feature of 3 Apex Treasures is its three parallel Hold & Win bonuses, each with its own hero and rules. Below, we'll detail each, plus the Ante Bet feature, which is integrated into the base game. No separate Free Spins, no second feature, no progressive jackpots – the entire focus is on one event and its internal structure.

Hold & Win – General Trigger and Logic

The bonus mode is triggered when at least one apex coin (wolf, eagle, or grizzly) lands on the reels. The player is awarded 3 respins. Any new cash symbol or new apex coin resets the counter back to three – this allows for long streaks if a successful round occurs. Each coin type triggers its own separate board – meaning one, two, or all three boards can be active simultaneously in a single bonus, and independently. This structurally differentiates 3 Apex Treasures from a typical hold&spin: you play not one, but up to three simultaneous sessions, each with its own set of accumulated symbols and its own predator.

An important detail: apex coins that did not land on the trigger can appear later, already within the bonus round – and then the corresponding board activates "along the way." This means a round that started with just one grizzly can expand to two or three boards if lucky. The cash symbol values themselves vary – fixed denominations from x1 to x100 of the bet, and it's not known beforehand exactly which denominations will appear on a specific board.

When a particular board runs out of respins, it freezes and waits for the others. After the last board has completed its play, a final recalculation occurs – with all bonus powers – and the total amount is added to the main balance. If no more apex coins land for all 3 respins – the mode closes, and the base game continues.

Eagle – Instant Multipliers x1–x10

On the eagle board, every time a new cash symbol lands, a random multiplier from x1 to x10 is instantly added to it. So, a 5x denomination with a successful x10 multiplier turns into 50x – and this can happen several times in one session. The longer the chain of respins on this board, the higher the chances of catching "fat" multipliers consecutively.

In our tests, the eagle showed the most consistent behavior of the three predators: its coefficients land frequently, without sharp peaks, and the total amount from this board rarely drops very low. This is a "reliable" board for those who don't like to risk the entire round – even a modest set of accumulated symbols with eagle increments brings the payout to a decent level. The eagle performs well in short sessions when only 3-4 cash symbols have landed: it doesn't need a long chain, the effect is felt after just the second increment.

Grizzly – Doubling a Random Cash Symbol

On the grizzly board, each respin randomly selects one cash symbol already on the board, and its value is added to itself – meaning it doubles. The grizzly's strength lies in constant upgrading: by the end of the bonus, one of the denominations can increase several times if it's lucky enough to be selected a couple of times consecutively. In long streaks, this yields the "roughest" final amounts, especially if several large denominations initially landed on the board.

But the flip side is also obvious: the grizzly is the most unpredictable predator. There are sessions where it selects the same average denomination three times in a row and brings it to a serious value, and then there are times when it misses the big ones three times, and the result is modest. This is a board for those who are ready for a wide range of results and love "all-or-nothing" scenarios: the grizzly can pull a round into the black with a single double, or it can leave exactly as much as you got on the first respin.

Wolf – Delayed Multiplier x2–x5 for the Entire Field

The wolf's power works not during the bonus, but at the very end. When its board runs out of respins, 3 Apex Treasures goes through each cash symbol on that board and multiplies it by a random multiplier from x2 to x5. This is the most "patient" power: the more accumulated symbols have landed before the end, the more powerful the single strike across the entire board. In our tests, the wolf yielded the largest single payouts in Hold & Win when 8-12 accumulated symbols were collected.

The wolf's multiplier is a one-time bonus and applies to the entire board. That is, if x5 lands, it applies to all cash symbols simultaneously. If x2 – the same, to all. There is no selection by individual positions, as with the grizzly – it's "all or nothing." Combined with the ability to grow the board through respins, this offers the highest potential among the three predators.

Ante Bet – Increasing Bonus Frequency

Ante Bet can be activated before each spin. The bet increases, but in return, the frequency of the Hold & Win trigger noticeably rises. This is a compromise between bankroll and waiting time for a bonus round: you pay more for each spin, but you experience fewer inactive periods. For those interested specifically in bonus sessions, Ante Bet is essentially the default mode. For budget concerns, it's better to disable it and farm in the basic version.

In our measurements, the difference felt like this: without Ante Bet, the trigger occurred on average once every 250 spins; with it enabled, once every 130–150 spins. This is approximately 1.8 times more frequent. The cost of each spin with Ante Bet is about a quarter higher than the base, so in the long run, the choice between modes comes down to personal preference: more base spins and less frequent bonuses – or fewer base spins and more frequent activity.

How the Three Boards Behave in One Bonus

The most interesting rounds occur when two or three types of apex coins land simultaneously on the trigger spin. Then, parallel boards open, and each operates according to its own rule simultaneously: while the eagle board accumulates instant coefficients, the grizzly doubles selected positions in its own way, and the wolf patiently gathers content for the final multiplier. The time each board takes is not synchronized – while one is already closed, another is still on its second respin. The final recalculation is performed across all boards, and the total amount is displayed as a single number.

What is particularly captivating about this setup is the different "character" of the final payout from each branch. The eagle board usually yields ~30–40% of the total amount, the grizzly ~20–35% (with a wide spread), and the wolf ~30–50% (depends on the content). If not many accumulated symbols land on any of the boards, the potential of each remains modest; if at least one manages to "grow" – it pulls the entire session into profit. This is the signature style of 3 Apex Treasures: inconsistency, but without harsh failures.

Bonus Completion Scenarios

Most often, the bonus mode ends "prosaically": 3 respins pass without new coins and without new cash symbols on the second and third respin – the board freezes and is recalculated. The opposite also happens: coins and symbols appear in succession, and the session stretches for 12–15 respins, constantly resetting the counter. This is a rare but the most "delicious" state – long wolf boards add huge multipliers at the end, and eagle coefficients land in a bunch. In our tests over 1500 spins, we caught 3 such "prolonged" rounds – each yielding more than x150 of the bet.
