Official mediaPlinky Plonky Collections
How collections gate progression in Plinky Plonky, what the Final Chance decides, and what the game page confirms about Collection 6.
A collection is the tier your current run is trying to clear, and the Final Chance jackpot is the gate. The update log on the official page names Collection 6 as part of Update 2, which tells you at least six tiers exist by then. Individual collection names and rewards are not published there as of 2026-10-19, so this category is honest about that limit.
