Cookie Run: Crumble Party Builder — Synergy Coverage Planner

Pick from all 69 launch Cookies and this builder does two things: it tracks your class balance, and it works out your Synergy coverage — which buffs your team actually turns on, which ones a Cookie is waiting on that nobody supplies, and the cheapest Cookie that would fix it.

Last updated: August 7, 2026.

Live, stranded and idle

Synergy in Crumble is one-directional: a Cookie either grants one to the team or receives one, and the two lists rarely line up by accident. The panel sorts your team’s Synergies into three states.

• Live — a Cookie on your team receives it and another one grants it. The buff fires.
• Stranded — a Cookie on your team receives it and nobody on the team grants it. That Cookie runs unbuffed for the whole fight. The panel names the cheapest provider that would fix it, by rarity first and cooldown as the tiebreak.
• Idle — a Cookie on your team grants it, but nobody on the team receives it. Not a bug in your team so much as a wasted half of a skill.

Stranded is the normal state, not the exception. Only 18 of the 69 launch Cookies grant a Synergy at all, so if you build by rarity — take your best pulls and field them — you will usually end up with at least one carry receiving nothing.

The supply is not gated behind rarity

The thing worth internalising before you spend materials: the cheapest fix is very often a cheap Cookie.

Five of the seven Synergies have a U- or R-rarity Cookie as their cheapest source. Knight Cookie is a U-rarity Tank and one of only four Range sources — Range being the Synergy 18 Cookies want. Grapevine Cookie is an R-rarity starter handed to you for free, and one of only two Rapid Fire sources against twelve Cookies that want it.

Pierce and Chain are the two exceptions, where the cheapest source is SR and there is no budget option at all. If your carry receives one of those, that is a real constraint on the team rather than something you can patch cheaply.

The reasoning behind each Synergy, including how long the buff lasts against the provider’s cooldown, is on the Synergy page.

How to build a good team

A safe template is a **frontline Charge + a Tank to anchor + Ranged Cookies for damage

• a Support** — see the full class guide. The builder warns you when your team has no Tank or no Ranged Cookie.

Then work backwards from your carry rather than forwards from your best pulls. Decide who your damage is coming from, read what Synergy that Cookie receives, and put a provider for it in the team before you fill the remaining slots. A provider is usually the cheapest Cookie in the team, so this costs you less than it sounds like.

One provider often covers several Cookies at once, because the receiving lists overlap heavily — 18 Cookies receive Range, so a single Knight can be feeding three of your picks simultaneously. That is why the panel counts how many Cookies are waiting on each Synergy rather than just naming it.

Sources

Rarity, class and element for all 69 Cookies from our roster data, cross-checked across PocketGamer, CrumbleDB, Pocket Tactics and cookierun.wiki. Skill names, cooldowns and the grants/receives lists from the per-Cookie /Crumble pages on cookierun.wiki, read August 5, 2026, covering 69 of 69.

The provider and recipient counts on this page are computed from that dataset rather than copied from anywhere, and the table under the tool is generated from the same two files the tier list and every Cookie page read, so the numbers cannot drift apart from the rest of the site.

We have not played the game ourselves. Nothing here is a tier claim — it is the Synergy graph, which is a fact about the roster rather than an opinion about it.
