What do the numbers do?
One block. Change the number, change everything.
Meet the block
Until now every block moved one step. This one has a number on it, and the number tells the command how much. Same block, different number — a totally different journey. Tap the number and it counts up: 1, 2, 3, 4, 5, then back to 1.
So this one block says: move right, four times — in one block instead of four.
See it work
Here is the same journey twice. First the long way, one block for every step. Then the same trip written with a number. Watch both.
Same journey — the number just says it shorter. Five blocks and one block landed the saucer in exactly the same place.
Your turn
Now you're the programmer.

Go further
Can you fly the same path with more blocks — or fewer?
Two ×1 blocks go exactly as far as one ×2. Try splitting a long block into small ones and watch the saucer fly the identical path, then put it back and see the block count drop.
For grown-ups
Parameters: one instruction, tuned with a value. That's how real code stays short.

Make a game other kids can play
The blocks on this page are a first taste. In a Kubrio project your kid builds a real game — powers, triggers, levels and all — and other kids get to play it.
