When Monopoly GO stickers reset, the sticker albums are completely wiped clean. All stickers collected are removed, giving players a fresh start. Unused Stars are also lost and do not carry over to the new album event. This means any Stars you haven’t used will disappear.
Additionally, if players don’t use their Stars before the season ends, these Stars are converted into dice rolls. This gives players another way to benefit from their unused Stars. A new sticker album then begins, allowing players to start collecting new stickers from scratch.
In brief, the reset in Monopoly GO means you lose your collected stickers and unused Stars. However, you get a fresh start with a new album and can still gain dice rolls from any leftover Stars. This keeps the game exciting and encourages continuous participation.
