How much does /undo cost?
The menu snapshot lists 400,000 Cash for /undo. Check the lobby purchase screen for the price and ownership details in the current build.
This is an unlock price, not a claim that the same amount is charged every time you type the command. The ordinary word list and the Meta Words shop serve different purposes.

How to unlock and use /undo
- Open the Meta Words menu in the lobby.
- Find /undo, check the displayed cost and unlock it when you have enough Cash.
- When you have a Writer turn, check which word was entered most recently.
- Type /undo, including the slash, if that last word is the effect you want to reverse.
Typing an ordinary word without the slash is not the same action as invoking the Meta Word.
What does “the latest word” mean?
The order of inputs matters. If Meteor is followed by another word before your turn, /undo should not be treated as a selector that lets you reach back and choose Meteor. The advertised target is the last word.
For example, imagine a wave is announced and then another player adds a new effect. Before spending your turn on /undo, read the latest announcement rather than assuming the wave is still the target.
Do not count on reversal to restore a player who has already been eliminated. Undoing an effect and reversing every consequence are different promises.
/undo vs /double vs /reset
- /undo: reverses the most recent word.
- /double: makes the next word happen twice.
- /reset: is a separate premium Meta Word described as resetting the world and healing players.
Choose based on whether you want to reverse an input, amplify the next one or use a broader reset. See all Meta Words for the separate unlocks.
