Ink Block Slider

Ink Block Slider is a sliding-block puzzle ground in lacquer, rice paper, and patience.

The master's seal — one vermillion block among black ink stones — is trapped inside a crowded wooden tray. Every block slides only along its grain: horizontal blocks glide sideways, vertical blocks rise and fall. No lifting, no turning. Just sliding, thinking, and the soft knock of wood on wood.

FREE THE SEAL
Work the other blocks aside, open the seal's road to the gate on the right edge of its row, and slide it out into the light. Every tray is a proven knot: each of the 20 puzzles was solved by exhaustive search before it was allowed into the game, so a way out always exists — the only question is how few moves you need to find it.

BRUSH MASTERY
Every seal freed pays ink shards. Spend them on permanent gifts: Brush Patience, which softens every par; First Ink, which makes the opening move of every tray free; and Second Bloom, which pays a bonus shard for every escape.
