Stream Sketch: Free Physics Drawing Game for Kids
Stream Sketch is a free physics drawing puzzle with 40 levels. Draw lines on the board and guide the falling drops into every cup. Later levels add coloured cups, filters that mix colours and limited ink.

What Stream Sketch trains
Stream Sketch practises physics intuition (predicting how gravity, slopes and flow move the drops), spatial planning (picturing a route before drawing it) and flexible problem solving: try, watch, undo, revise. Colour mixing and limited ink on later levels reward sequencing and efficiency.
What the research says: Predicting how the drops will fall before drawing combines spatial reasoning with planning, and spatial skills are among the most trainable thinking skills (Uttal et al., 2013).
Who Stream Sketch is for
Stream Sketch suits Grades 1–7 and up. Starter (Grades 1–2) has one tap, ramps and walls. Explorer (Grades 3–4) adds a second tap, shelves, pegs and covered cups. Challenger (Grades 5–6) brings colour filters and mixing to make violet. Expert (Grade 7+) limits the ink and combines every mechanic.
How to play Stream Sketch
- Drag on the board to draw a line. Drops slide along it.
- Fill every cup; the number shows how many drops it still needs.
- Coloured cups only count drops of their colour. Send drops through filters to change them.
- Bonus: guide a drop through the hidden EyeQBoost eye.
- Stuck? Pause to plan, undo, or watch one solution and then find your own.
Tips for parents and teachers
Before they draw, ask “Where do you think the drops will go?” Try playing together: one plans the route, the other draws it, then swap. Use the answer as a last resort, then ask for a different route. Short sessions of 10 to 15 minutes a few times a week work best.
FAQs
What age is Stream Sketch for?
Grades 1–7 and up, roughly ages 6 to 14. The first levels need just one line; Expert limits the ink.
What does Stream Sketch teach?
Cause and effect, early physics (gravity and slopes), spatial planning and creative problem solving. There is usually more than one way to solve a level.
How many levels are there?
40 levels across four stages, plus a hidden EyeQBoost eye bonus to find.
What if my child gets stuck?
Pause to plan, undo the last line, or double-click Answer to watch one solution, then try a different route of their own.
