A Timber Stacks spin can continue after its last tumble appears to finish. One reel stack may fall and expand the usual 5×5 board as far as 10×5, creating up to 100,000 ways for another evaluation. Because the enlarged shape resets afterwards, the defining event is a temporary second chance rather than permanent reel growth.

Tumbles before the timber falls
Animal symbols form left-to-right ways on five reels and five rows. Mountain wilds appear on the middle three reels and replace ordinary icons. Every win disappears so new symbols can tumble into its positions, and the process repeats while another matching way exists.
After the final winning combination, one stack may drop and add rows across the reels. The larger board is checked again before returning to 5×5. Extra positions create possibilities, not an automatic award; matching symbols must still connect from the left under the same ways rule.
Expansion also belongs to free spins
Four or more scatters award at least eight free spins. Each bonus turn can use the same post-tumble expansion, so its board may also reach ten rows and 100,000 ways. The provider does not state that the enlarged shape persists from one free spin to the next.
More starting spins give the expansion additional opportunities to occur, while the optional 120x purchase changes access only where permitted. Neither route ensures that every turn grows or that the widest layout forms a win. Grid size and symbol connection remain separate conditions.
High-volatility configuration
Pragmatic Play released Timber Stacks on 6 November 2023 and lists 96.05% RTP, high volatility and a 10,000x maximum. The active operator screen should confirm RTP and feature availability.
Its strength is the surprise continuation after a cascade seems complete. The weakness is timing: expansion arrives late and disappears quickly. Readers who like variable geometry have a clear event to watch, whereas anyone seeking lasting progression may find the reset abrupt.
Timber Stacks layers temporary reel growth onto a conventional tumble sequence. A normal ways win clears symbols, later combinations settle, and only then can the stack create a larger final board. Free spins repeat this logic instead of introducing an unrelated collector. The design is coherent because the extra height has a precise lifetime, but it remains dependent on useful symbols arriving after expansion. High volatility and the 10,000x cap frame the reference version; neither reaching 10×5 nor seeing 100,000 ways is itself a paid result. This final expansion is meaningful precisely because it changes the available ways without changing the underlying matching rule.
