Yoshi and the Mysterious Book Review: How a Cozy Sandbox Reinvents a Classic

Players are given almost no upfront hand-holding. Instead, every level is “entirely driven by your own experimentation and discovery” . You’re dropped into a sandbox-size stage, presented with a creature, and told to figure out what it does — by licking it, throwing it, watching how it behaves in different environments, and seeing what happens when you use it on other objects. Only after you start interacting do soft objectives reveal themselves . This “discovery loop” replaces the traditional goal of simply reaching the end of a stage .

The biggest Yoshi gameplay shift in years

Previous Yoshi games moved players from point A to point B through curated obstacle courses. Yoshi and the Mysterious Book breaks that pattern completely:

• Sandbox-style stages — Each level is a large, open-ended space with wildly varying size and scope. You’re encouraged to roam freely and experiment rather than follow a fixed route .
• Research missions, not goal flags — Levels are framed as research missions tied to a specific creature. You select a creature from Mr. E’s pages, enter its habitat, and the mission’s objective isn’t spelled out — you discover it by poking at the world .
• Creature cataloging — Every interaction teaches you something new about the creature, which gets logged in an in-game encyclopedia. Big discoveries grant three stars; small ones grant one. Stars unlock new chapters and worlds .
• Emphasis on replayability — Because 100% completion is where the real engagement lives, levels support multiple playthroughs with different approaches. Vandal calls the replayability “impresionante” (impressive) .

One reviewer at Galaxus coined the genre “cozy platformer-sandbox with creature-collecting elements,” and the label stuck . Others, such as Kotaku’s roundup, described the game as “breezy, charming, shallow, fun” — a compliment in context, aimed at players who approach the game with the right level of curiosity .

Tetris 99 54th Maximus Cup event

Nintendo is celebrating the launch with a collaborative Tetris 99 event. The 54th Maximus Cup (called the Grand Prix in Europe and the Teto Cup in Japan) runs from May 29 through June 1, 2026, though some Japanese sources show an extended window that ends June 2 depending on time zone calculations .

To participate, you need a Nintendo Switch Online subscription and must play Tetris 99’s standard online mode during the event. Placement in each match awards event points. Once you accumulate a total of 100 points, you permanently unlock a Yoshi-themed in-game skin featuring art, music, and Tetrimino designs inspired by Yoshi and the Mysterious Book .

The promotion was confirmed directly on Nintendo’s store page and via an official trailer that dropped on May 26 . As with past Maximus Cups, the theme is exclusive to the event — there’s no word on whether it will be available for purchase afterward .
