Sumthread
One Path. Every Number.
Free · Designed for iPad. Not verified for macOS.
A clever little break. One path. Every number. Trace a single thread through every tile, earn the Clean Weave seal, and return each day for a fresh Daily Thread.
Sumthread is a calm, tactile number-path puzzle crafted for a thoughtful five-minute break.
One rule governs every board: trace a single continuous path through every tile on the grid—moving up, down, left, or right with no diagonals and no revisits—while hitting the ordered Target Sums at the top in exact sequence.
Each time your running sum reaches the active target, that tile locks in a warm amber checkpoint ring and your next segment begins from zero. The final target sum must finish on the last remaining tile of the board.
FEATURES
• One Continuous Thread: Drag fluidly across adjacent tiles or tap step-by-step. Backtrack anytime by dragging backward or tapping an earlier tile on your path.
• Next-Step Reach & Exact-Match Cues: Subtle dashed borders highlight orthogonally reachable neighbors, while warm amber indicators mark adjacent tiles that complete your active target sum.
• Clean Weave Mastery: Complete any board with zero hints and zero undos to earn the Clean Weave seal.
• Daily Thread: One fresh 4×4 board generated each day with local completion history and spoiler-free emoji grid sharing.
• Automatic Local Save: Pause mid-path on any board and pick up at your exact step whenever you return.
• 5 Curated Puzzle Collections: Progress from approachable 3×3 Starter Threads and 3×4 Morning Break boards to demanding 4×4 Deep Weave, Quiet Sunday, and 4×5 Grand Tapestry grids.
• Editorial Board Themes & Accessibility: Play in Warm Ivory, Charcoal Dark, Newsprint Cream, Deep Forest, or Clay & Ochre, with optional step-order badges and high-contrast tile borders.
