Block Fit
Every piece has exactly one home
About Block Fit
Fit an odd-shaped set of blocks into the board with no gaps and nothing left over. Rotate and flip until it clicks — every puzzle is generated fresh and always has a solution.
Ankhdase tracks 3 distinct skills in Block Fit, including Spatial reasoning, Strategy & planning and Shape attributes. Because mastery is estimated per skill rather than per game, the questions shift toward whatever a student is getting wrong — and away from what they have already proved they know.
How to play
- Drag a piece onto the board. It only drops where it fits exactly.
- Tap a piece in the tray to rotate it; double-tap (or press F) to flip it.
- Fill every square with nothing left over to finish the puzzle.
Skills Block Fit practices
- Spatial reasoning
- Strategy & planning
- Shape attributes
Mastery is estimated separately for each of these, which is what lets the difficulty move independently — a student can be fluent on one and still be fed easier questions on another.
Questions about Block Fit
- Is Block Fit free to play?
- Yes. Block Fit is free, runs in any modern browser, and needs no download or plugin. You can play straight away without an account; signing in is only needed if you want progress, streaks and badges saved.
- What age is Block Fit for?
- Block Fit suits ages 5–adult — roughly Kinder to Adult. The difficulty adapts as you play, so it stays useful across that whole range rather than being pitched at one year group.
- What does Block Fit teach?
- It practices Spatial reasoning, Strategy & planning and Shape attributes. Every question is tagged with the skill it exercises, so progress is tracked skill by skill rather than as one overall score.
- Does Block Fit work on a tablet or phone?
- Yes. Block Fit works with touch as well as a mouse, and every drag action has a tap-to-select alternative. Once the page has loaded once it also keeps working offline.
- Can teachers assign Block Fit?
- Yes. Teachers can create a class, add students in bulk without email addresses, and set Block Fit as an assignment with a goal — a score, a number of minutes, stars or a typing speed. Progress updates automatically as students play.
