Wonderland launched on August 14, 2026 at noon, simultaneously on Mobile, PC, and Console with no staggered rollout (RobloxDB). The original planned launch was August 8 at 2:00 PM EST / 7:00 AM CET; Roblox moderation rated the experience as 16+ about one hour before that window, and ScaryPlay pulled the release, appealed the rating, and launched six days later with no age restriction (Fandom wiki, BloxInformer, ProGameGuides).
Wonderland is a co-op mascot-horror roguelike built by MUCDICH and ivasmigins (the core team behind The Mimic) alongside polybadge, ObscureWithin, and cucoda (FAQ wiki). Up to five players share three lives per run and traverse randomized levels in a sinister theme park; the soundtrack is composed by Ampient (non-copyright, per the live Roblox description).
Story Mode is locked at launch and is targeted for 2027; Levels Mode is the active experience (Fandom wiki). Players who join the ScaryPlay Roblox group receive in-game rewards (verbatim from the live Roblox description).
