Pome Thrive is completely free and ad-free — and the Shop doesn't change that. Everything here is an optional in-game item meant to buy you more room to maneuver when the box gets crowded, not a way to unlock the game itself or its core mechanics. Every run plays out the same way for every player.
Items can be earned for free in-game through regular play and daily challenges. If you'd rather stock up faster, item packs are also available for purchase through Google Play's official payment system. All purchases are optional — the core gameplay is identical for every player, and there's no scenario where you have to pay just to start a run.
Item effects above are inferred from the in-game icons. If the actual mechanics differ, let us know the exact rules and we'll correct this section.
