Success in Simple Gako requires that every cell, edge, region, and fixed clue satisfies the row column frequency clues completion test. The game declares completion only after all interacting restrictions agree at the same time.

Complete guide
Simple Gako uses the independently implemented Simple Gako row column frequency clues rules v1 profile (R663). The defining decisions in Simple Gako come from this rules combination: Each cell contains a number telling how often that same number appears across its row and column together.
The Simple Gako opening separates permanent constraints from player-controlled positions. Each cell contains a number telling how often that same number appears across its row and column together. Its versioned seed recreates those same constraints locally while keeping unrevealed decisions out of the guide and board labels.
Simple Gako treats the printed or dealt restrictions as hard constraints, not suggestions. Each cell contains a number telling how often that same number appears across its row and column together. A move that contradicts the current state has no effect, including after the game has ended.
Success in Simple Gako requires that every cell, edge, region, and fixed clue satisfies the row column frequency clues completion test. The game declares completion only after all interacting restrictions agree at the same time. Close Simple Gako by auditing the boundary cases first and the obvious placements second. The position is not done until every cell, edge, region, and fixed clue satisfies the row column frequency clues completion test.
For each candidate digit, count its current and possible occurrences across the crossing row and column, remembering that the shared cell is counted once. Adding separate row and column counts without subtracting the cell double-counts its own value and makes every apparent frequency clue one too large.
For each candidate digit, count its current and possible occurrences across the crossing row and column, remembering that the shared cell is counted once. This matters specifically because each cell contains a number telling how often that same number appears across its row and column together.
Adding separate row and column counts without subtracting the cell double-counts its own value and makes every apparent frequency clue one too large. Recheck the legal boundary before choosing a replacement move.
Finish Simple Gako when every cell, edge, region, and fixed clue satisfies the row column frequency clues completion test. Completion is checked from the entire position, not from a displayed answer or a visual approximation. Undo and redo expose alternative branches without revealing an authored answer.
