Tetris 99 is running a limited-time promotion that cuts the price of 41 collaboration themes to two tickets each, allowing players to buy them directly without earning points. The event gives players another opportunity to obtain themed cosmetic packs, including some linked to past special events, before it ends on 17 August 2026.

Available themes span major Nintendo franchises such as Animal Crossing, Zelda, Mario, Kirby, Pokémon, Splatoon and Xenoblade Chronicles. Each theme includes customised backgrounds, music and sound effects; notable options include Animal Crossing: New Horizons, Super Mario Bros. Wonder, Pokémon Legends: Arceus and Xenoblade Chronicles X.
