Tools & boosters
Undo the mistake—or change the board?
The official listing identifies Undo and Shuffle as available tools. Their value depends on the problem you are solving: a bad last move or a board with too little access.
Use Undo when…
- You can name the move that removed your last flexible space.
- A pour buried the only accessible copy of a needed color.
- You noticed a stronger destination immediately after moving.
Best question: “What was better one move ago?”
Consider Shuffle when…
- No short sequence exposes the colors you need.
- The useful matches are buried across several mixed bottles.
- Undoing one move would not repair the underlying layout.
Best question: “Is the whole position the problem?”
Run this check before spending a tool
- Find the target colorChoose the color closest to a complete bottle or most likely to release space.
- Trace two movesIf one temporary parking move exposes it safely, you may not need a booster.
- Identify the failureA known last-move error points to Undo; a locked layout points toward Shuffle.
- Inspect the resultAfter using a tool, recount empty and semi-flexible positions before moving again.
Tool availability is based on the official store description. Exact limits, costs, and effects can vary by version, so this guide does not hard-code them.
