Use every number to find 404

Drag numbers from purple boxes into the dark green box to make 404. A successful 404 changes the destination box to orange.

How the game works

Click a number in the destination box to remove it. The stated completion condition asks you to find every 404 and use all the numbers from the purple boxes.

A practical starting point

Before committing the final number, check both the total and which source numbers remain. Removing one entry lets you revise the combination instead of starting a new guess blindly.
