Rain 2026 dropped on March 12 with update V1.913 and runs until March 26. It's the second adventure of the year and the fourth time the Rain event has come back since its debut in 2016. If you've played any previous Rain or Frog event, the core loop is familiar — but there are a few things worth knowing before you jump in.
The whole concept is dead simple. You stand on a platform at the top of a waterfall, the platform disappears, and you tumble down through a field of bouncy obstacles like a pinball. Where you land determines your reward. No skill required — just luck and a bit of positioning.
When the event map loads (it rotates in between normal rounds), you spawn near the top of a tall waterfall map. There's a temporary wooden platform up there. Pick your spot — left side, right side, dead center, wherever you think gives you the best landing. Once the platform releases, you're locked in. Can't move, can't change direction. You can still dance or throw confetti if you want to look cool while falling, but that's about it.
On the way down, raspberries and mushrooms act as bumpers. They'll bounce you sideways, slow you down, or fling you into a completely different section. There are 7 landing sections at the bottom, each with different reward pools. If you get really unlucky, you might still be bouncing when the round timer ends — in that case you miss out entirely. Doesn't happen often though.
Quick note: you need at least 4 mice in the room for the event map to appear. Playing in a busy vanilla room gives you the most chances to see it. The event interval between appearances changes every server restart, so some days you'll see it every few minutes and other days it takes a while.
Rain 2026 gives you two types of chests when you land in a section:
One random reward from any past event in the game's history. Could be a title from Halloween 2013, a badge from Epiphany 2019, a shop item from Christmas 2022 — anything. Great way to fill gaps in your collection.
One random reward from past Rain or Ninja events specifically. More focused pool — if you missed items from Rain 2016, 2021, or the Ninja events, this is your shot to grab them.
Both chests can drop titles, badges, orbs, shop items, or emojis. The rewards are random each time, so there's replay value in running the event map as many times as you can during the two-week window.
There isn't really a "meta" for Rain — it's fundamentally a luck-based event. But here's what experienced players have noticed across four years of this event:
The first Rain event launched on February 29, 2016 — deliberately timed with the leap day. The frog theme is a play on "frogs leaping." Pretty clever for a game about mice. That 2016 version introduced the pinball waterfall mechanic that every Rain event since has reused.
Rain came back in 2019, 2021, and now 2026. The 2021 version added the chest reward system where items from past events get recycled into loot pools. The core gameplay hasn't changed much across versions — Atelier 801 kept the formula because players genuinely enjoy the chaotic randomness of it.
