Ultrapool Patch Notes & Update History
Every officially posted Ultrapool patch in one timeline — from launch week to the v0.17.2 Halloween update — with the changes that actually affect builds.
Latest: v0.17.2 — the Halloween update (5 Oct 2026)
- New: 14 seasonal snacks in the snack bar, Halloween bar decorations and bartenders — and Creative Mode, unlocked by beating an All-Nighter, where you can freely test any ball and snack combination.
- Balance: Eyeball nerfed to 20/40/60/80/100%; Time Machine nerfed above Level 2; Aliens now scale target count (1/2/3/4/5) with a lighter nudge; buffs to Fridge, Snake, Bear, Zombie, Incubator, Witch, eggs (x1–x5 per level), Log, Luna, Screw and Vampire.
- Rules: Ooze is now 'Spawn & Pocket:' (was 'Spawn:').
- Fixes: Gummy bear and worm passives now ignore untargetable balls like imps; a new visual appears when a spawn is blocked by the 30-ball limit.

Why the version list jumps
Not every build gets a public post. The official feed jumps from v0.15.7 to v0.17.2 — interim builds (the 0.16.x–0.17.1 range) were not announced on Steam, so any balance detail for those builds is in-game only. This page mirrors what the developer posts; in-game behaviour is the final word.
What the changes mean for builds
- The developers actively rebalance scaling pieces — Eyeball has now been nerfed twice (v0.15.0, v0.17.2). Treat any 'unbeatable build' as patch-dated.
- Spawn mechanics keep getting fixes and limit visuals (30-ball cap) — spawn engines are supported but capped.
- Mobile QoL (cloud saves, battery saver) means cross-device runs are now practical for daily players.
- Every guide on this site states its patch context — if a page says v0.17.2, its claims were checked against the Halloween update.
