Horochi's Challenge

Horochi's Challenge is a single-player 3D puzzle game that combines pushing crystal orbs with changing gravity. Guide the orbs to their goals, connect the power circuits, and bring the computers to life.

Choose your floor. Change gravity in six directions.

Look around each stage with the mouse, then choose which of its six faces should become the floor. Orbs and characters fall toward the new gravity direction.

Push an orb first, or change gravity first? Use fixed blocks, rail platforms, and moving pillars to work out the right order of actions.

All 100 stages selectable from the start

Choose from NORMAL 01–50, HARD 51–75 and EXTRA HARD 76–100 across five worlds: grassland, forest, town, castle and demon castle.

No completion requirement stands between you and EXTRA HARD. Try a tough puzzle first, or switch stages when you get stuck. Separate uncleared, cleared and minimum-move medal markers track your progress.

EXTRA HARD: XOR gates, water levels and larger 3D mazes

Take on 25 additional puzzles, with five in each world. Plan switch states, water levels, character positions and gravity changes to navigate larger mazes.

• XOR gates open when exactly one of their two switches is ON. Both ON or both OFF closes the gate, so choose what to leave on each switch. An occupied gate stays open until it is clear.
  
• Water controls: stand a character on a water control panel and choose low, middle or high water. Floating platforms carry the characters and orbs riding on them up or down.
  
• Floating platforms follow vertical guides and keep their height when gravity changes. Each water-level change counts as one move; ceilings or fixed obstacles can block it.
  
• Cutaway view: select a layer to inspect the maze without using a move.

HARD mode: pressure switches and orb anchors

HARD adds five puzzles per world, for 25 stages in total. New mechanisms make it even more important to decide what should move, what should stay put, and when to change gravity.

• Pressure switches keep matching gates open while a character, orb, or moving pillar rests on them. Decide what to leave behind to hold a gate open.
  
• Orb anchors catch falling orbs and hold them in place through gravity changes. Push an orb from the side to release it.
  
• Where an anchor overlaps a switch, secure an orb to keep the gate open while you explore a route from another gravity direction.

Position Meguru and Bimba together

In stages featuring both characters, switch between them as you solve the puzzle. Gravity affects your partner too, so plan where both characters will land before choosing a direction.

Find a solution, then earn the minimum-move medal

A stage's minimum move count is revealed after your first clear. Solve it your own way, then return to find a shorter solution. A minimum-move clear on your first attempt earns the medal too.

Watch your clear replay and save it as a video. Collect minimum-move medals on all 50 NORMAL stages to unlock a special reward from Horochi.

PC controls and room to experiment

• Move with WASD or the arrow keys. Drag the mouse to look around and use the wheel to zoom.
  
• Choose a gravity direction with the globe UI or keys 1–6, then confirm the change.
  
• Undo a move or reset the stage to try another idea.
  
• Learn the rules through Meguru and Bimba's short skits and live 3D demonstrations.
  
• Japanese and English text and voice clips, two music tracks, and adjustable sound, graphics, and language settings.
