Ultrapool Seeds Guide
Seeds decide what your run offers: the shop, the snacks and the cubes. This guide covers what is known about seeded runs, the community's special 'ludwig' seed, daily challenge seeds — and the honest answer to 'what is the best seed?'.
What a seed changes
A seed is the string that drives the game's randomization. Officially, Ultrapool ships with seeded and unseeded runs plus a Daily Challenge that uses the same seed for everyone. The detailed rules below are community-catalogued, not officially published:
- Shop balls — the same offers when the seed, the number of rounds played (including lost rounds) and the total rerolls match.
- Snacks — the same offers when the seed, the current level and the snack tickets used match.
- Cubes — the same cube when the seed and the current level match.
How to play a seeded run
Custom seeds are an official feature ('seeded and unseeded runs' on the store listing). The community-catalogued route: pick the seed option at run start, enter a string, and the run becomes deterministic — the same string offers the same shops, snacks and cubes to everyone who plays it the same way. Exact menu wording changes between patches; if you cannot find the field, check the run-start screen and settings in the current build.
The 'ludwig' seed
The community has catalogued one named special seed: ludwig — it randomizes like a normal seed but only offers a single Cubert cube. Winning a game on the 'ludwig' seed is also tied to a hidden achievement (LudwigW). Both facts are community-catalogued, not officially documented.
Daily challenge seeds
The Daily Challenge runs on the same seed for every player, which is what makes the leaderboards comparable — and why the community plans daily routes in advance (some players even scout with a second profile, a community-catalogued trick). Daily strategy basics live on the difficulties page.
How to find strong seeds (the honest answer)
There is no official seed list and no verified 'best seed' for Ultrapool yet. Anything claiming an exact best seed string is either community folklore or unverified. What you can do today:
- Pick a seed, play it, and note what the shop offers each round — shop contents are deterministic per seed, rounds played and rerolls.
- Compare seeds on the same early rounds: a seed that offers a spawner or a multiplier before round 3 is doing the heavy lifting.
- Share and collect seeds where the community gathers (the official Discord and the subreddit) — when a verified strong-seed list exists, it belongs on this page.
Seeds and achievements
At least one hidden achievement is seed-specific: LudwigW for winning on the 'ludwig' seed (community-catalogued). The full unlock lists are in the achievements guide and the hidden achievements page.
FAQ
Common questions about this topic.
What is the best seed in Ultrapool?
There is no official or verified best-seed list yet. Seeds are deterministic, so the way to find a strong one is testing and community sharing — see the hunting steps above.
How do I enter a custom seed?
Seeded runs are an official feature; the seed field appears at run start in the current build. Exact menu wording is not documented and can change between patches.
What does the 'ludwig' seed do?
Community-catalogued: it randomizes like a normal seed but only gives one Cubert cube — and winning on it unlocks the hidden LudwigW achievement.
Do seeds affect achievements?
At least one hidden achievement is seed-specific (LudwigW on the 'ludwig' seed). Whether other achievements are seed-sensitive is not documented.
How does the daily seed work?
The Daily Challenge uses the same seed across accounts, so daily leaderboard scores are comparable. Scouting the daily in advance is a community-catalogued strategy.
