You complete Dotchi Loop when one closed loop visits every white circle, avoids every black circle, and gives each room a consistent white-circle passage type. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.

Complete guide
Dotchi Loop uses the independently implemented Nikoli Dotchi-Loop rules v1 profile (R448). Dotchi Loop is a complete deterministic browser game whose distinct rules centre on one non-branching loop in which every white circle inside the same room must be used uniformly as either a turn or a straight passage.
Dotchi Loop opens from a versioned seeded position built for one non-branching loop in which every white circle inside the same room must be used uniformly as either a turn or a straight passage. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
Every Dotchi Loop action is checked against the current board, available material, and this defining restriction: a loop vertex has degree zero or two, and white circles in one room may not mix turning and straight behaviour. Invalid, stale, or post-terminal actions leave the position unchanged.
You complete Dotchi Loop when one closed loop visits every white circle, avoids every black circle, and gives each room a consistent white-circle passage type. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim. Near the end of Dotchi Loop, recount the remaining obligations needed until one closed loop visits every white circle, avoids every black circle, and gives each room a consistent white-circle passage type. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
A practical Dotchi Loop plan is to preserve several legal continuations around one non-branching loop in which every white circle inside the same room must be used uniformly as either a turn or a straight passage. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing. A common Dotchi Loop error is to ignore the boundary rule that a loop vertex has degree zero or two, and white circles in one room may not mix turning and straight behaviour. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
Dotchi Loop has its own runtime and save identity because its rules require one non-branching loop in which every white circle inside the same room must be used uniformly as either a turn or a straight passage.
a loop vertex has degree zero or two, and white circles in one room may not mix turning and straight behaviour.
Dotchi Loop stores its game ID, rules version, and seeded deal identity. Those values recreate the same opening locally without promising that the position is forced or winnable.
