Challenge Mode is a challenge where you have to guess several Pokémon, one after another, until you run out of attempts. You have 7 attempts per Pokémon. Your health bar will refill each time you guess a Pokémon correctly, so you don't have to worry about using too many attempts on a single one.

However, Challenge Mode doesn't work the same way as Daily Mode. You'll have to choose which of the seven available clues you want to reveal in order to guess the Pokémon and move on to the next round. But be careful — any clues you use in one round won't be available in the next, so choose wisely.

Challenge Mode is intended to be very difficult, so try your best. You may play up to three times per day. How long those games come to be depends on your own knowledge. Good luck, and have fun!
