How to play
- Goal
- Shade rooms so the open maze has one route from S to G, through every circle and no triangle.
- How it ends
- The chart finishes when all open cells connect without loops and neither colour makes a 2×2 block; Undo and Erase allow corrections.
- Record
- Your first unassisted finish keeps your time for that chart; later plays are practice.
- Every thick outline is a room. Shade all of it or leave all of it open. Rooms containing S, G, circles or triangles always stay open.
- All open cells must connect orthogonally without forming a loop. Branches and leaves are allowed.
- The unique route from S to G passes through every circle and no triangle. Triangles stay open on branches off that route.
- Neither shaded nor open cells may fill a 2×2 square. Shaded rooms may touch along edges or corners.
- Choose Shade, Open or Erase, then tap rooms or paint a stroke and release. Dots are optional open notes; blank rooms count as open at completion.
- Undo and Redo allow corrections. Restart keeps the first clock running. Reload retains the exact unfinished marks and Undo, and that resumed finish stays local. Practice reopens fresh and cannot replace the saved first time.

Tips for Nurimeizu

- Prevent squares Neither colour may fill a 2×2 block, and longer open loops are forbidden too.
Questions about this game
Do triangles have to be shaded?
No. Their rooms stay open, but the S–G route must avoid them.
Can the open maze branch?
Yes. Every open cell connects, and there are no loops. Only the S–G route must visit the circles.
Can shaded rooms touch?
Yes, along edges or corners, as long as shaded cells do not fill a 2×2 square.
Do I need to dot every open room?
No. Blank unshaded rooms already count as open; dots are optional notes.
Can replay improve my first time?
No. Your first saved finish remains unchanged; replay is practice.
All charts are open. Reload retains an unfinished first attempt, Undo and its original clock; resumed finishes stay local. Practice reopens fresh and preserves your first time.

About Nurimeizu
Shade whole outlined rooms to make one open maze from S to G. The route visits every circle and avoids every triangle.
All 160 original charts are open: forty 4×4, eighty 5×5 and forty 6×6 mazes across four shelves. Each has one answer and can be solved through visible deductions.
Your first finish keeps its time for that chart. An uninterrupted verified first solve can claim the named fastest time; later plays are untimed practice.
