Sand Shape Level 142 Walkthrough
Sand Shape Level 142 is a five-column I2/I3 bar board with mixed Similarity and Difference markers. Lock pink I3 and peach I2 on the top bar, match yellow and green as I3 down the neck, plant the cyan/blue ears, grow purple to I3 unlike cyan, then close the lower columns with maroon, orange, lime, chartreuse, sky, violet, and magenta.

How to Solve Sand Shape Level 142 — Full Solution
- Fill pink as the top-left horizontal I3 on the top bar.
- Fill peach as the top-right horizontal I2 on the remaining top-bar cells, keeping the top-right triangle join unlike yellow’s I3.
- Fill yellow as the neck horizontal I3 under the two top Similarity diamonds so yellow matches pink’s I3.
- Fill green as the horizontal I3 under yellow across the neck Similarity diamond so green matches yellow’s I3.
- Fill cyan as the left-ear vertical I2 beside green, unlike green across the left upper triangle.
- Fill blue as the right-ear vertical I2 beside green, unlike green across the right upper triangle.
- Fill purple as the full mid-left vertical I3 under green beside cyan; grow past any short I2 so the left triangles stay unlike cyan’s domino.
- Fill maroon as the centre vertical I2 under green’s middle above the future sky cells.
- Fill orange as the mid-right vertical I2 under green beside maroon.
- Fill lime as the lower-left vertical I2 under cyan in the left column.
- Fill chartreuse as the lower-right vertical strip under blue in the right column.
- Fill sky as the bottom-centre vertical I2 under maroon.
- Fill violet as the bottom-left I2 under lime into the lower-left corner.
- Close magenta as the bottom-right I2 under orange and chartreuse into the last cream cells, then verify every diamond pair matches and every triangle pair differs.
Colors in this level:
Pink, Peach, Yellow, Green, Cyan, Blue, Purple, Maroon, Orange, Lime, Chartreuse, Sky, Violet, Magenta
Common Mistakes to Avoid
- Leaving purple as a short I2 that matches cyan across the left Difference triangle.
- Extending peach into an I3 so the top-right triangle joins two trominoes.
- Shrinking yellow or green to I2 so a neck diamond joins unlike lengths.
- Painting any bent L or S stroke; only straight dominoes and trominoes clear Required Shapes.
Quick Tips for Sand Shape Level 142 (spoiler-free)
- Keep peach as the short top-right I2 so it stays unlike yellow’s neck I3 across the top triangle.
- Grow purple to a full I3 beside cyan’s I2 — a short purple dab is the video’s Difference fail.
- Name reused hues by region: upper green under yellow versus lower-left lime and lower-right chartreuse; left-ear cyan versus bottom-centre sky.
Board notes 5 details
- Layout
- A cream robot/T polyomino: five-cell top bar, three-cell neck centred under the bar, five-column body with left/right ears. Similarity diamonds: two on the top-bar/neck join under pink, one on the neck/body join under yellow. Difference triangles: top-bar/neck join under peach, left ear wall, right ear wall, upper centre cross, and four lower vertical stubs.
- Goal
- Tile every cream cell with only straight I2 dominoes and I3 trominoes so every diamond-marked join pairs matching lengths and every triangle-marked join pairs unlike lengths.
- Opening
- The verified run fills pink as the top-left horizontal I3, peach as the top-right horizontal I2, yellow as the neck I3 under the top diamonds, then green as the I3 under yellow across the neck diamond.
- Danger Zone
- A short purple I2 beside cyan matches cyan’s ear domino across the left triangle and flashes Difference red X — grow purple to a full vertical I3. Pink and yellow must both stay I3 across the top diamonds; peach must stay I2 so the top-right triangle against yellow remains unlike.
- Mechanics
- Required Shapes shows a vertical I3 and a vertical I2 (rotations allowed). Similarity connects same shapes; Difference connects different shapes across fourteen straight-bar regions.
Frequently Asked Questions
What silhouettes does Sand Shape Level 142 require?
Only straight bars: the I3 tromino and the I2 domino. Horizontal and vertical orientations are allowed; bent shapes are not.
What is the safest opening for Sand Shape Level 142?
Fill pink as the top-left I3, peach as the top-right I2, yellow as the neck I3 under the top diamonds, then green as the I3 under yellow before planting the cyan and blue ears.
Why does Level 142 flash a Difference red X beside cyan?
A short purple dab is also an I2, so it matches cyan across the left-ear triangle. Extend purple to a full vertical I3 so the join pairs unlike lengths.
How many colour regions does Level 142 need?
Fourteen straight-bar placements. Reused hues (green/lime/chartreuse, cyan/sky) always refer to different regions.
