How to play
You complete Ripple Effect when each room contains every integer from one through its size exactly once and all equal digits satisfy their separation rule. The full Ripple Effect position determines the outcome; visual shortcuts never replace the documented Ripple Effect terminal rule.
- Ripple Effect begins with a grid divided into rooms of varied size with some fixed digits and all other cells awaiting values. The Ripple Effect deal identity and Nikoli Ripple Effect rules v1 are stored together. Restarting Ripple Effect reproduces this opening exactly.
- During Ripple Effect, you enter a digit valid for its room and clear it later, while room completeness and horizontal or vertical ripple distances are checked. The Ripple Effect engine rejects profile violations, unavailable material, and every action attempted after Ripple Effect reaches a terminal result.

Strategy tips
- A reliable Ripple Effect plan is to complete small rooms, then eliminate values whose same-number peers lie within the forbidden row or column distance. A Ripple Effect hint is legal and deterministic. The next Ripple Effect hint exposes one bounded action; it never claims a forced Ripple Effect win.
- A costly Ripple Effect mistake is to measure only cells between equal digits; their coordinate distance itself must be greater than the repeated digit. Undo supports studying that Ripple Effect decision, while restart preserves the original seeded Ripple Effect opening.
- In the Ripple Effect endgame, cross-check the last room permutation against all row and column ripples before choosing its final arrangement. Check every remaining Ripple Effect action before committing because its terminal rule is enforced immediately.
