Turn wisps of nectar into a kingdom of real butterflies. Merge stages, unlock rare species, and watch your garden thrive — even offline.
Turn a single butterfly into a thriving kingdom in this cozy idle-merge adventure.
Start with a humble Cabbage White fluttering through a meadow and work your way up through sixty real-world and fantasy species — Monarchs, Blue Morphos, Swallowtails, Birdwings, and beyond — each one rendered as an actual butterfly photograph inside a hand-drawn storybook world.
IDLE PROGRESSION, NO PRESSURE
The garden keeps working while you're away. Come back to pockets of nectar, stock up on gems, and watch your butterflies level from fragile first flight to maxed-out royalty. Offline earnings cap at 8 hours, so you never miss the fun.
SIXTY REAL BUTTERFLIES TO DISCOVER
Every tier is a carefully chosen species from the public-domain photographic archive — Monarch, Painted Lady, Blue Morpho, Queen Alexandra's Birdwing, Apollo, and many more. Tap any tier in your Collection to read its stage, peak nectar yield, and the poetic name you've unlocked. Six biomes take you from the Meadow to the Empyrean Zenith.
BOOSTERS, SUBSCRIPTIONS & METAMORPHOSIS
Speed through tiers with 2× or 3× nectar boosters, keep a permanent 2× Forever unlock in your back pocket, or subscribe to VIP Weekly / Monthly for daily gems and a 1.5× rate multiplier. When you're ready to reset, Metamorphosis trades your accumulated tiers for permanent Pollen — a forever multiplier that carries across every new garden.
FULLY LOCALIZED
Play in English, Simplified Chinese, Spanish, Japanese, French, German, Portuguese, Russian, or Korean — everything from tier names to legal text is translated.
RESPECTS YOUR TIME
No ads. No account required. No tracking. Your progress is stored locally on your device; wipe it any time from Settings.
Butterfly Kingdom is made for people who love cozy incremental games, collecting real nature photography, and watching a tiny garden grow into an empire of wings.
