Timber Stacks

Timber Stacks by Pragmatic Play features a 5x5 grid with 3,125 ways to win initially, expanding randomly up to 10x5 for 100,000 ways through the Increasing Grid Size mechanic. After wins, the tumble feature removes paying symbols, allowing new ones to drop from above until no further combinations form. One reel (typically 2-5) may fall left or right into a new bottom row, with fresh symbols filling gaps, before the grid resets post-tumbles. Symbols include low-paying card royals (10-A), medium animals like fish, mountain lions, and owls, high-paying bears and wolves, wild mountains on reels 2-4 substituting for others except scatters, and coin scatters triggering free spins (8 for 4 scatters, 10 for 5). Bets range from 0.20 to 240 per spin, with ante bet option increasing stake 25% for doubled free spins chance, and bonus buy available. RTP stands at 96.05-96.5% depending on operator, with high volatility. Visuals depict a frosty wilderness theme with timber stacks as reels, animals, and mountains, paired with dynamic grid shifts for engaging, unpredictable gameplay that differentiates it via reel-falling expansion rather than standard modifiers.
