Challenges

Challenges are game modes with specific objectives. They do not have high scores or leaderboards, but instead give ranks based on the turns taken to complete the objective.

The turncount is counted when you tap the "Finish" button. If you continue playing and tap Finish later, your current turncount will be counted. If you quit without tapping Finish, your turncount will not be counted.

To get S rank for a challenge, finish it within 300 turns.

The base game comes with the Limited Space challenge. Each Pack includes three more challenges, which match with the theme of the Pack.
