Ultrapool Beginner Guide: How to Play and What to Buy First

What a run actually is

Ultrapool looks like pool and scores like a deckbuilder. You rack a triangle of balls, take a set number of shots, and every ball you pocket adds its score. Each round has a target; clear it and you survive, miss it and you lose a life. On the default difficulty a run is 10 rounds long.

The part that makes it a roguelike is what happens between rounds. Score above the target turns into money, and the game is explicit about the formula: surplus is scaled to the triangular number and rounded down, so seven extra points (1+2+3) pays £3. Overshooting by a little pays almost nothing; overshooting by a lot pays properly. That single rule is why experienced players stop aiming to “just clear” the round.

Money buys balls at the bar. More balls means a busier table, and a busier table means more opportunities for effects to chain off each other. That is the whole loop: clear, overshoot, buy, clear harder.

The three things a new player misreads

Rarity is not power. The game labels balls Common, Uncommon, Rare and Legendary, and it is tempting to treat that as a shopping list. It is not. Sand is a Common whose effect reads “Receive buff: Score that amount x1” — in a board that hands out small buffs, it is one of the strongest balls in the game. Meanwhile Overflow Ball is a Legendary that does nothing at all unless you have committed to number balls. Read the effect, not the label. The ball tier list sorts the 121 catalogued balls by what their effect text actually does.

Flat score does not scale. A ball that gives +1 gives +1 in round 2 and +1 in round 9, while the score target keeps climbing. A ball that multiplies, copies itself, or buffs the whole board grows with the run. When you can only afford one thing, buy the one that compounds.

Triggers matter more than numbers. Effects fire on specific events: pocketing this ball, pocketing any ball, hitting a wall, receiving a buff, another ball spawning. Two balls with similar-sounding effects can be worlds apart because one fires once per round and the other fires every time anything happens. The trigger tags on the ball database are there to make this scannable.

Your first five purchases

Nothing here is a fixed shopping list — the shop is random — but these are the shapes worth spending on when they appear.

1. Anything that adds multiplier. Pants (Legendary, Classic) increases the multiplier of two random pockets on every pocket; Reaper (Rare, Spooky) gives a pocket +1 mult and drags in a loose ball. Multiplier applies to everything you sink afterwards, which is the only effect in the game that gets better the better the rest of your board is.
2. A copier. Mirror Ball spawns a level 1 copy of your front ball every round; Nesting doll unpacks into a smaller version of itself each time it is pocketed. Free bodies are free triggers.
3. A global buff. Window gives +1 to all your balls and flowers on pocket, and Butterfly — a Common — buffs every ball twice a round. On their own these are modest. Paired with Sand or Gaia, they become the engine.
4. One cheap economy ball. Golden Ball pays +2€ per pocket and Piggybank can be grown and then sold for gold equal to its score. Money in round 3 is worth far more than score in round 3.
5. Whatever your set is built around. Every set has a spine: numbers and pockets in Classic, flowers and buffs in Nature, scrap and upgrades in Tech, transformation in Spooky, spawning animals in Friends. The sets page has each one’s plan in a sentence.

Reading the table, not just the shop

Two habits separate a first-time clear from a first-time loss.

Aim for the pocket you have invested in. Several effects add score or multiplier to a specific pocket rather than to a ball. Once a pocket has been fed, keep feeding it — a pocket with +2 mult turns every ball you sink into it into double value.

Take the long shot when the table is crowded. Balls with “hit wall” and “collision” triggers (Bricks, Egg, Marble, Bomb) pay for ricochets. A shot that clips four balls on its way to a pocket can fire more effects than a clean straight pot.

What comes next

Clearing Chill Night with one set unlocks Wine Mixer for that set, which opens the snack bar and mixes two foreign sets into your shop. That is the point at which runs stop being about your starting set and start being about what you can assemble.

The full ladder — and what each rung changes — is on the difficulties page. When you are comfortable, the build guide covers the specific ball pairings that turn a survivable board into a scoring engine.
