A Brainy Dungeon battle: answering "Mars" correctly lets Lantern Fox hit the Crystal Jelly. Answering "Atlantic" instead of "Pacific" lets the jelly strike back, and Lantern Fox blocks it.
How it works

Your brain is the weapon. Your monster is the hero.

01

Hatch your partner

Pick an egg and meet Lantern Fox or Moon Rabbit. Same strength, different style. You can switch any time in your Bag.

Answer to attack

Every right answer is a hit. Get one wrong and your monster blocks, then shrugs it off. The real answer waits for you in the recap.

Grow and evolve

Clear dungeons for EXP and coins. Level up, gear up, and watch your partner evolve through three stages.

Meet your partner

Two starters. One glow-up each.

Each monster carries a light that grows as it does. It starts small and cute, and ends up ready for the toughest dungeons.

Lantern Fox

Male starter

A dusk-blue fox with a lantern on the tip of its tail. The lantern grows from a faint ember to a bright flame, and finally to a glowing crystal.

  • Ember
  • Flame
  • Crystal
Moon Rabbit, stage 1 Moon Rabbit, stage 2 Moon Rabbit, stage 3

Moon Rabbit

Female starter

A snow-white rabbit with a little moon on its forehead. The moon waxes from a crescent to a half moon, and finally to a full moon.

  • Crescent
  • Half moon
  • Full moon

Dress for the dungeon

Spend the coins you earn on swords, armor, and fun hats. Gear shows up on your monster in every animation, at every stage.

  • Dawn Sword
  • Crystal Armor
  • Explorer Hat
  • Gold Crown
  • Moon Tiara
The dungeons

Four dungeons. A whole world of facts.

Each dungeon covers one subject and has four tiers, from Easy to Expert. Harder questions bring bigger rewards, and the enemies get a little tougher looking. Never scary.

Science

Crystal Cave

Space, the body, and how things work. Watch out for the Crystal Jelly.

Crystal Jelly
History

Ancient Ruins

Empires, inventions, and great journeys. Guarded by the sleepy Old Jug.

Geography

Volcano Valley

Mountains, oceans, and islands. Home of the grumbly Tiny Volcano.

Floating Library

A bit of everything, from art to animals. Ask the Question Book.

Question Book

With a slice of Indonesia. Some questions explore Indonesia's islands, history, and culture, each written with enough context for players anywhere in the world.

Fun over pressure

Play at your pace. Nothing gets taken away.

No countdown clock

Take your time to think. Quick answers earn a bonus hit, and a slow answer is never marked wrong.

Every run pays

Even a tough run sends you home with coins and EXP. Levels and evolutions never go down.

Care is a bonus

Feeding and playing give your monster extra Spirit for bigger rewards. Forget for a week and nothing is lost.

Out of energy? Keep learning

Relaxed practice uses no energy and gives unlimited hints. Energy refills while your monster rests, even with the game closed.

Learn from every miss

After each dungeon, the recap shows the right answer with a short explanation. Mistakes turn into new facts.

A free hint every run

Stuck? A hint removes one wrong answer. You get one free each run, and you can buy one more with coins. Hints are never sold for money.

Between runs

Come home to a cozy cave.

Your monster rests by the lantern while its energy refills. Toss it a ball, or share a snack inspired by Indonesian treats, like sweet klepon or a mini tumpeng.

  • Klepon
    + Spirit
  • Mini tumpeng
    + more Spirit
