What You're Up Against
Sand Shape Level 131 is a logic-based region-packing puzzle on a 6×6 grid. Every region must contain exactly four orthogonally connected cells. Pre-drawn lines between symbols dictate constraints: identical shapes (e.g., triangle–triangle) linked by a line must fall within the same region; different shapes (e.g., triangle–infinity) linked by a line must be in separate regions. No cell may belong to more than one region.
Beating Sand Shape Level 131
- From triangle at (1,3), draw down to form a vertical 1×4 orange region covering (1,3), (1,4), (1,5), and (1,6).
- From triangle at (1,1), create a 2×2 yellow region: (1,1), (2,1), (1,2), (2,2).
- At (4,1), build a 2×2 green region: (3,1), (4,1), (3,2), (4,2) — contains triangle at (4,1) and infinity at (4,2), which are unlinked, so this is valid.
- The infinity at (3,4) is linked by a line to the triangle at (1,3) (orange region), so it must be isolated. Form an L-shaped light blue region: (2,3), (3,3), (2,4), (3,4).
- Fill the bottom-middle gap with a purple 2×2 region: (2,5), (3,5), (2,6), (3,6).
- Complete the right-side column with a red 1×4 region: (4,3), (4,4), (4,5), (4,6).
Doing It Faster
- Prioritize symbol pairs connected by pre-drawn lines first — they lock in critical region boundaries early.
- Use simple shapes (2×2 squares, 1×4 lines) where possible; reserve L-shapes only for constrained gaps.
- Visualize each region’s four cells before drawing — counting prevents overflows or underfills.
- This walkthrough skips trial-and-error by anchoring around the (1,3) triangle and its linked (3,4) infinity — the core constraint.
Where Players Slip Up
- Forgetting that all regions must be exactly four cells — common errors include 3-cell or 5-cell zones.
- Misreading line rules: assuming adjacency = linkage, or ignoring that only pre-drawn lines enforce grouping/separation.
- Overlooking that the (3,4) infinity and (1,3) triangle are different symbols and linked — forcing them into separate regions is non-negotiable.
- Rushing step 4: placing the light blue region incorrectly breaks the separation rule, derailing the entire solution. Sand Shape Level 131 hinges on this constraint — get it right, and the rest flows.
