# Puzzle Summer on Base App

<figure><img src="/files/myAGQTSLVwnGXmO03E8W" alt=""><figcaption></figcaption></figure>

Puzzle Summer is a limited-time leaderboard event running until the end of August. Every spell chess puzzle you solve earns points. The higher your score, the greater your share of the 1% $CHECK token allocation reserved for Anichess Puzzles.

Your total score is calculated from all three competitive puzzle modes:

* Daily Puzzle Points ×5
* Universe Stars counted directly
* Rush Mode Bonus added daily based on your best placement

The leaderboard tracks your cumulative score throughout the event. Top performers will earn $CHECK based on final placement when Puzzle Summer ends.<br>

You can boost your score by inviting friends through your Base App referral code:

* Each free user earns you +3 energy.
* Each premium user gives you +50 points, +1 max energy, and 10% of their leaderboard score.

There’s no cap. More friends means more fuel for your climb.
