Solki: Cube Builder Kids
3D shape puzzles, ages 4-10
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Three shadows, one solid. Your child builds a shape that matches all three views at once - and learns to see in 3D. 168 hand-made levels. No ads, no data, no reading.
Solki turns three flat shadows into one solid shape - and your child is the one who builds it.
Three cards sit at the top of the screen: what the shape looks like from the front, from the side, and from above. The workbench below is empty. Tap a square, a cube drops onto it. Keep going until all three shadows match.
No text. No typing. No reading required.
WHAT YOUR CHILD LEARNS
• Seeing in three dimensions - the skill behind maps, diagrams and drawing
• Reading a plan and a side view, the way engineers and architects do
• Holding two rules in mind at once, then three
• Finding the cheapest answer, not just an answer
THREE WORLDS, ONE WORKBENCH
Shadow (ages 4-6) - one card. Copy what you see.
Two Eyes (ages 6-7) - two cards, then three. Now the views argue with each other.
Hollow (ages 8-10) - cubes float. Dozens of shapes cast the same three shadows; find the one that uses the fewest cubes.
BUILT FOR SMALL HANDS
Turn the workbench to see the hidden side. Every edge is colour-coded to its card, so nobody loses their bearings. Hold a cube to take it back. Nothing is ever lost, nothing is ever timed, and there is no way to fail.
HOW WE MADE THE LEVELS
Every level is solved by a program before it reaches your child. That program proves the puzzle is possible, and works out the fewest cubes it can be built with - that number is the three-star target. No level was guessed at, and no star threshold was typed in by hand.
WHAT SOLKI WILL NEVER DO
• No ads. Not now, not later.
• No data collected. No analytics, no tracking, no accounts, no network code at all.
• No permissions. Not the camera, microphone, location or notifications.
• No subscription. One purchase unlocks every level, forever.
• Works offline.
Made by one person who wanted his own children to have something quiet to think with.
