Cinderseam is a volcanic number-logic game built around one extra clue: every glowing seam means the two neighbouring stones differ by exactly one. Dark joints matter too — they tell you the numbers are not consecutive. Fill each basalt slab so no number repeats in any row, column, or box. Start with compact 4×4 boards, then move into larger 6×6 and 8×8 chapters where seam patterns, sparse starting stones, and dark-joint deductions become part of every solution. Features: • 24 handcrafted slabs across Vent, Caldera, Rift, and Forge • Glowing seams that reveal consecutive neighbours • Dark joints that become essential clues in later chapters • Fair cracks: only visible-rule mistakes are penalized • Chalk notes, Undo, Quench, and optional Glimpse help • Three-star results based on clean solving • Carved marks for leaving short notes on completed slabs • Cosmetic stone and seam sets unlocked with earned Embers • Progress saved automatically on your device Read the slab, follow the seams, and cool every challenge from the first vent to the final forge.
