4 Wolf Drums Slot Review

Fixed Mini, Minor, Major and Grand jackpot symbols can appear in the bonus. Filling the ordinary screen may also award Grand. A named jackpot arriving on a symbol and a full-screen objective are distinct routes, so the visible board should not be read as one single jackpot counter.

Collect gathers symbol values already visible. Multi places multipliers into random empty cells, preparing positions for the symbols that can subsequently occupy them. One effect acts on existing prizes; the other changes the properties of a position.

If another multiplier lands on a cell that already has one, that cell's multiplier increases by one. The rule is an incremental increase, not an instruction to multiply the displayed numbers together. Tracking the highlighted cells explains why a later symbol can arrive in a different-value position from an otherwise similar symbol nearby.

Mirror adds two rows, extending the original five-by-three field to five-by-five. It can copy a symbol from one added row to the other. This gives the extra area a function beyond simply providing more empty positions.

Filling the expanded board with Mirror active may award Royal, which the provider lists at 5,000×. That target is separate from the ordinary-screen Grand condition. Expansion creates a larger collection task; it does not mean the remaining positions are guaranteed to fill before the round resolves.

Master Drum can activate during the bonus and send Bonus symbols or Mini-to-Grand jackpot symbols into empty cells. It can also reset respins or activate a feature that was previously inactive. A round therefore need not retain exactly the feature combination with which it began.

Watch the respin counter and active-Drum indicators after an intervention. The important information is what changed on that event: additional prizes, another attempt, an awakened feature, or a combination. Master Drum is a possible action during play, not a player-controlled way to keep the counter alive indefinitely.
