One-Click Undo

Undo Move

Reverts the most recent connection step, whether it was drawing a line segment or placing a colour change. Can be used multiple times in succession to step back through several actions, making error correction straightforward.

Usage details:

• Each purchase provides one undo charge.
• Works independently; multiple charges can be stored.
• Does not restore spent items or hints.

Undo Move is applied instantly and cannot be reversed — the reversal itself is a new action that can be undone with another charge.
