World of Slime on Mobile

Searches for “World of Slime iOS,” “Android,” “pre-registration,” and “mobile release date” all point at the same calendar TEAM42 has repeated since the gameplay trailer: mobile pre-registration in November 2026, then a simultaneous PC and mobile official launch in December 2026. The Steam demo that went live on 26 August 2026 is not that client. It is a Windows PC preview. This page is the phone timeline, the official-site signup, and the traps people fall into when they try to install the demo on a tablet.

What is confirmed

Inven’s trailer coverage (and later demo coverage) states the journey as: Steam demo in August, mobile pre-registration in November, official launch on PC and mobile in December. Gamemeca and GameChosun repeat the same three beats. The English marketing site worldofsli.me still leads with “Launching December 2026” and a signup block that collects date of birth, Kakao/SMS or email, and consent checkboxes — a Korean-facing waitlist, not an App Store listing. iOS and Google Play store pages are not live at the time this article was written. When they appear, roadmap and this page will link them. Until then, a Steam wishlist on app 4671450 remains the PC notify channel.

Cross-play between PC and mobile is the stated design for that December launch. TEAM42 has not published the account-linking flowchart (Steam login on iOS, a studio ID, or something else). Read cross-play for confirmed versus guessed. Do not promise your guild that a phone can join the Windows demo this week. It cannot.

What the live demo is not

The demo store (app 4793900) is Windows only. There is no TestFlight, no APK, and no “World of Slime mobile demo” on the stores. Steam lists Touch Only Option as a category on the game pages because the full design includes a complete touch scheme. That flag is not a download button for August. If you only own a phone, your actions today are: wishlist on a PC if you have one, join Discord from worldofsli.me for the Explorer role, and wait for November’s pre-registration window. The download demo page is for people with Windows.

Steam’s full-game Mac block (macOS 12, M1 or Intel i5, 8 GB, 20 GB) is also not a phone. Mac is a December Steam SKU in the plan, not an iPad port of the current demo.

November: G-STAR and the waitlist

November 2026 does double duty. TEAM42 said it will meet players at G-STAR in Busan with more detail, and that mobile pre-registration opens the same month. Those are two doors, not one. A booth hour is not an App Store push notification. The official site’s email/Kakao form is the public waitlist TEAM42 already runs. Completing it does not install a game. It tells the studio how to reach you when store pages exist.

If you are outside Korea, the Kakao path may not apply. Use the email option on the English page if it is offered, and still wishlist Steam. This wiki does not scrape rotating form URLs into the article because they change. Use the button on worldofsli.me.

December: one launch, two device families

The official site and press describe a chewy MMORPG you play with friends: Cubes, synthesis, Slimepedia, 1v1-to-3v3, forests / mountains / graveyards. That loop is meant to be the same fantasy on a phone and a PC. Touch Only Option and Camera Comfort on Steam are the accessibility story for small screens and motion — see accessibility. TEAM42 has not published a separate mobile system-requirements table (SoC names, RAM). Do not copy a random “Snapdragon list” from a forum.

Progress from the Windows demo still does not carry. A nickname claimed in the demo is a social stake described by GameChosun, not a phone save — nickname. When the mobile client exists, assume a fresh Slimepedia unless Steam News says otherwise.

Monetisation does not change on a phone

TEAM42 removed gacha. Paid items are convenience and cosmetics. That pitch does not grow a creature banner because you opened the Android client. The monetization page stays the source. Ignore “World of Slime codes for mobile” videos until the codes hub has a real string.

Practical checklist

1. If you have Windows: install the demo, claim a name, learn Cubes.
2. Wishlist the full Steam app regardless of your future main device.
3. Join Discord via the official site.
4. In November, complete official pre-registration when the store buttons exist; keep G-STAR hours on events.
5. In December, install the real mobile client from Apple or Google — not a sideload of the Steam demo.

The phone is late on purpose. The Windows demo is the handshake. December is the room where PC and mobile were always supposed to meet.
