Reach the target by combining the six numbers with +, −, × and ÷. Pick a number, an operation and a second number: the two are replaced by their result, which you can use in the next step like any other. Each number can be used once, you need not use them all, and every result must be a whole number above zero — a step that would break that cannot be pressed.
Any way of reaching the target counts. Undo takes back the last step and Start again takes back all of them. With a keyboard, type + - * / for an operation and Backspace to undo.
Four draws. The first can be done in two steps, the next in three and then four, and the last cannot be done without all six numbers. Each tells you when you matched the fewest steps possible.
Work backwards from the target: find a multiple of a large number close to it, then make up the difference with the small ones. The day prints well if you prefer to work it out on paper.
A new day starts at midnight UTC. Your progress is kept in this browser, so you can leave a day half done and come back to it, and every day already published stays playable from the archive.
