- Fill yellow as the left-mid tetromino covering the left-mid leaf under peach.
- Fill lime as the mid-left L tetromino weaving the left hole ladder and covering its leaf.
- Fill cyan as the centre corridor tetromino weaving the mid holes and covering its leaf.
- Fill blue as the upper mid-right C tetromino around the mid-right hole covering its leaf.
- Fill purple as the top-right vertical tetromino covering the top-right leaf.
- Fill mauve as the mid-right tetromino under purple covering its leaf.
- Fill orange as the lower-right rail tetromino under mauve covering the lower-right leaf.
- Fill chartreuse as the bottom-right bar tetromino covering the bottom-right leaf.

Colors in this level:
Pink, Peach, Yellow, Lime, Cyan, Blue, Purple, Mauve, Orange, Chartreuse, Green, Sky
Common Mistakes to Avoid
- Flooding the lower cream after mauve so two bottom leaves share one region.
- Extending any mid corridor stroke until a second leaf shares the region.
- Leaving a two- or three-cell stub that fails the area-4 card.
Quick Tips for Sand Shape Level 138 (spoiler-free)
- Finish the left pink/peach/yellow/lime rail before entering the mid corridor.
- Name reused hues by region: left peach rail versus lower-right orange; mid-left lime versus bottom-left green.
- After mauve, close the bottom as four separate one-gem tetrominoes.
Board notes 5 details
- Layout
- A tall irregular cream polyomino has a top-centre notch, dual bottom feet, a ladder of internal brown square holes, and twelve green leaf gems spaced so each final tetromino owns exactly one.
- Goal
- Partition every playable cell into twelve connected four-cell regions so each region contains exactly one green leaf.
- Opening
- The verified run fills pink as the top-left bay, peach as the left-upper vertical, yellow as the left-mid block, then lime as the mid-left L around the left holes.
- Danger Zone
- Any stroke that covers two green leaves fails the gem card; stubs that are not exactly four cells fail the area card; after mauve, do not flood the lower cream as one mega-fill — split orange, chartreuse, green, and sky.
- Mechanics
- All regions' area must be 4; each shape has exactly one green leaf gem. No Similarity or Difference markers.
