Official mediaPlinky Plonky Upgrades
The three upgrade layers in Plinky Plonky: coin-bought boards and gadgets, ball forging, and the rebirth skill tree.
Spending in Plinky Plonky splits across boards, upgrades and gadgets bought with coins, forging that turns weak balls into rarer ones, and rebirth tree nodes paid for with points. On top of that sit optional Roblox passes. The official page does not itemise upgrade names or prices as of 2026-10-19, so this category maps the layers and says which details are known.
