Nintendo has unveiled an update for Tetris 99 (version 2.5.0) introducing a new method to acquire past event themes. Unfortunately, the English patch notes are unclear due to translation issues from Japanese.
As highlighted on BlueSky by @OatmealDome, the patch notes suggest exchanging themes for in-game tickets. However, it’s clarified that the update allows purchasing previous themes for 30 tickets each, not selling them.
You can now obtain past event themes through the Customize menu. Each theme costs 30 tickets.
The available themes are:
- WarioWare: Move It!
- Metroid Dread
- Monster Hunter Rise
- Mario Golf: Super Rush
- Miitopia
- Super Mario 3D World + Bowser’s Fury
- Super Mario All-Stars
Version 2.5.0 also includes general improvements to enhance gameplay comfort. The English patch notes are expected to be corrected soon.
