The Multifly mechanic in detail
5x3 / 243 ways format
5 columns × 3 rows with 243 ways to win (any combination of 3+ matching symbols left to right on adjacent reels). Symbols: colorful butterflies (low pays), exotic flowers (mid), rare exotic butterflies (high pays). A polished butterfly-nature universe.
Dropdown wins — the cascading base
Standard cascading mechanic:
- Winning symbols disappear after each combo
- New symbols drop from above to fill the empty spaces
- The cascade continues as long as there are wins
That's the foundation — but Multifly adds a unique layer on top.
Individual reel multipliers — the signature mechanic
This is what makes Multifly stand out in the market. Each reel has its own individual multiplier:
- All reels start at x1
- Every winning Dropdown involving that reel bumps its multiplier up by +1
- The multiplier applies to every payline running through that reel
- Multipliers are persistent for the session (they never reset)
In practice: if reel 3 sits at x5 and reel 4 at x3, a payline crossing both gets multiplied by x5 × x3 = x15 (compounding). It's exponential.
Automatic Wilds on winning positions
An additional bonus mechanic:
- On every winning Dropdown, a Wild lands automatically on one of the winning positions
- The Wild bumps the reel multiplier of that reel by +1
- Cumulative effect: the longer a Dropdown chain runs, the more Wilds and multipliers stack up
This is what can turn an average spin into a big session via a long cascade chain plus stacked wilds and multipliers.
Free Spins — persistent cumulative multipliers
Trigger: 3+ scatters → Free Spins.
- Multipliers accumulate across the whole FS session (no reset)
- Wilds appear more frequently
- Final combo = pot × multiplier × wilds = potential max win of 10,000x
In tested FS sessions: average payout of 80-300x the stake per trigger. With heavily stacked multipliers (4-5 reels at x5+), payouts can climb to 1,000-2,000x.

Multifly strategy
With high volatility and a 10,000x max win, here's what to keep in mind:
- Flat bet of €0.40-0.80 across 200-300 spins (max bet €75 — lower cap than Pragmatic's €100)
- Target bankroll: 80-100x your stake to absorb the variance
- Free Spins target: roughly 1 trigger per 100-150 spins
- Multiplier strategy: don't change your stake mid-session — reel multipliers are persistent, so switching stakes wastes the progress you've built
- In FS, never stop early (cumulative multipliers reward patience)
