HOW TO PLAY
How to play Tunnel Seal
Build a tunnel network outward from the central core. Match every connection where pieces touch, rotate or replace pieces while supplies last, and seal all reachable exits to win.
Controls
- Select a piece, rotate it, choose a board cell, then place it; touch players can tap each control.
- Press R to rotate, N to start a new tunnel, Enter to place, or X to replace a piece while supplies remain.
Tips
- Check every open edge in the connected network before placing a piece.
- Use replacements while supplies remain and plan how new connections affect the reachable exits.
