They're right behind those paper doors. Can you spot the tell?
Ninja Seeker is a retro pixel arcade game about one simple thrill: spot the hidden ninja, throw the shuriken. Enemies hide behind Japanese paper doors — the only tell is a door pushed up ever so slightly — and a sliver of a foot peeking out beneath. Aim, throw, THUD.
EASY TO PICK UP
- One round takes about 30 seconds — perfect for a quick break
- One finger, one motion: tap the door, smash the ninja
- Plays offline, no ads, no account needed
SPOT THE TELL
A door hiding a ninja rises just a little: obvious on Easy, a mere 1.5 pixels on Hard. Train your eyes, trust your instinct, and strike before time runs out — every hit lands with satisfying vibration feedback.
DEPTH WHEN YOU WANT IT
- 9 ninja arts: shuriken, bomb, fire, poison, water, ice, wind, thunder — plus a screen-clearing Fuma Shuriken ultimate
- Climb the castle: 110+ handcrafted levels across 4 floors, then an endless mode that never stops scaling
- 5 boss masters, each a different duel: clone-spotting, hide-and-seek, memory bombs, bullet hell, and a rhythm sword duel set to Beethoven's Fate Symphony
- Advanced Challenges: all five masters return remixed and harder. Every player gets one free run per day
- Train five abilities: Observation, Patience, Memory, Stamina, Agility. Beat each master's forms to fill your ability radar — master all five to earn "Five Paths Mastered"
- A story told in manga-style cutscenes, a codex of characters and lore, and detailed play stats
