1 Million Megaways BC Slot Free at Monster Casino
Iron Dog Studio dropped something ridiculous in 2020: the first slot to break past one million ways to win. Not theoretically — actually. The Mammoth Reel mechanic pushes the Megaways engine to 1,058,841 combinations during free spins, which is frankly excessive in the best way. At Monster Casino you can test this prehistoric chaos in demo mode or chase that 45,000x max multiplier for real.
The base game runs 6 reels with standard Megaways (64 to 117,649 ways), but once you trigger free spins by landing four consecutive tumbles, a seventh Mammoth Reel appears in the center. That reel expands up to 9 symbols tall and hosts sticky wilds that lock in place for the entire feature. Plus, there’s a reel-locking system borrowed from Pirate Kingdom Megaways: when any reel maxes out its height, it locks and awards extra spins.

Core Mechanics & Tumble System
Winning symbols vanish, new ones tumble down, and a multiplier ladder kicks in with each cascade. First tumble: 2x. Second: 4x. Third: 6x. Fourth and beyond: 8x. That multiplier resets only when the tumble sequence ends or free spins begin.
Four consecutive tumbles light the fire meter and award 8 free spins. Keep tumbling beyond four, and you get 2 extra spins per tumble (maximum 14 spins from 7 tumbles). During free spins, multipliers no longer reset between non-winning spins, so they can compound aggressively if tumbles keep flowing.
🔥 Expert Tip: Focus on extending tumble chains in the base game — each consecutive cascade inches you closer to the free spins trigger while stacking multipliers up to 8x.
Symbol Payouts & Wild Mechanics
| Symbol | 7-of-a-Kind Payout |
|---|---|
| 10 / J / Q / K / A | 20x stake |
| Irish Elk | 40x stake |
| Sabretooth Tiger | 60x stake |
| Woolly Mammoth | 80x stake |
| Cavewoman | 100x stake |
| Caveman | 140x stake |
| Standard Wild | Substitutes all regulars (reels 2–6) |
| Sticky Wild | Mammoth Reel only, locks for entire feature |
Sticky wilds appear only when the Mammoth Reel locks at full 9-symbol height during free spins. Once locked, up to 9 sticky wilds can remain for every remaining spin, dramatically increasing win frequency and multiplier stacking potential.
