Multiple Choice

caution

Multiple Choice challenges are only available on Hosted CTFd instances or with the purchase of the Multiple Choice CTFd plugin

Multiple choice challenges allow users to select a single flag from a list of choices.

Within the description message you can insert choices for your multiple choice question using the following syntax:

* () Choice 1
* () Choice 2
* () Choice 3

You can then copy the correct choice as a flag.

For example with the following description you will get something like the below image.

* () The Cake
* () 42
* () The Red Umbrella
* () All of the above
