Sand Blocks: manage the pile, not just the shape
Sand Blocks is a colour-matching puzzle by Onki Games in which placed shapes break apart into loose sand. Connect the left and right walls with a continuous group of one colour to clear it before the pile crosses the upper limit. The connecting path can bend as grains settle; it does not need to form a straight row.
Quick facts
- Sand puzzle developed by Onki Games
- Three offered shapes at a time
- Matching sand connects the two side walls
How to play
Study colours near the bottom and choose a shape that can extend their connection toward the opposite wall. You may use the three offered shapes in any order.
- 1
Choose a colour and landing area
Look for a same-colour group already reaching one wall. Compare the offered shapes and find a drop that can extend that group across the remaining width.
- 2
Drop and observe the flow
Drag the selected shape onto the playing area and release. Watch where its sand settles; it will not retain a rigid block outline.
- 3
Connect both walls before the pile climbs
Join the left and right walls with one connected sand colour. After that group disappears, reassess the pile’s height and the changed surface before dropping again.
Controls
Desktop controls
- Hold the left mouse button to pick up a shape, drag it into position, and release.
- Choose any of the three offered shapes; you do not have to follow their left-to-right order.
Phone and tablet
- Desktop is recommended for this distributed build.
- Phone play has not been validated; the provider currently labels this version as not mobile ready.
What makes this puzzle different
Shapes become grains
A piece can spread as it settles, so a narrow landing point does not guarantee that the colour will remain narrowly contained.
A connected colour bridge
The in-game guide asks you to connect the two side walls with one colour. A mixed-colour span does not meet this condition, while a continuous same-colour path can rise and dip.
Practical placement tips
- Use the choice among three shapes to extend a colour group toward the opposite wall instead of automatically dropping the first piece.
- Avoid feeding a tall mound unless the drop can help connect its colour to the other wall. A low adjacent area may offer safer room for the sand.
- Recheck the surface after each clear: grains can settle into the newly opened space, changing where your next colour is needed.
Who might enjoy it
Fans of sand physics puzzles
The shifting surface suits players who enjoy observing how a placement changes after it lands.
Players looking beyond rigid blocks
This offers a different problem from filling stationary square cells: colour continuity and pile height work together.
Score, goals and the end of a round
The survival rule is to keep sand below the upper limit. The current game’s tutorial explicitly asks for same-colour connections between the left and right walls; its example uses curved bands, not straight rows. Clearing a connected group recovers room. Watch the entire surface: a low middle does not protect a tall pile near one side.
Game questions answered
How do you clear sand in Sand Blocks?+
Create a continuous group of one sand colour touching both the left and right walls. Its route can bend through the pile; the current in-game guide does not require a ruler-straight horizontal row.
Must I use the three shapes in order?+
No. The published instructions allow any order, making the choice of which shape to place first part of the puzzle.
Why does my placed shape fall apart?+
That is the main mechanic. Each offered shape turns into sand and settles, so judge the resulting pile rather than expecting a solid tetromino.
Can I rely on Sand Blocks working on my phone?+
This embedded version is recommended for desktop. The distribution page marks it as not mobile ready, and phone controls have not been validated.

Try one colour connection
Choose the shape that helps a low colour group reach the opposite wall, then let the grains settle before deciding again.
