Ristnumber on nagu ristsõna, aga tähtede asemel on numbrid.
Iga küsimuse vastus sisaldab vähemalt ühte nulli. Enne ruudustikku kirjutamist tuleks vastusest eemaldada täpselt üks null. Näiteks kui 1P vastus oleks 30204, siis tuleks ruudustikku kirjutada 3024 või 3204.
Kui küsimuses viidatakse mõne teise küsimuse vastusele, siis peetakse silmas esialgset arvu (enne nulli eemaldamist).
A numbri taga tähistab "Alla" ja P tähistab P "Paremale"
2A - 1P + 6P + 9P + 10P
3A - 10P / 4
4A - Algarvu aste
5A - (4A x 8P) / 7A
7A - Faktoriaal

Crossnumber is like crossword, but there are numbers instead of words.
Each answer contains at least one zero. Exactly one zero should be omitted when writing answer to the grid. For example, if answer ot 1R would be 30204, you should write 3024 or 3204.
When an answer is referred in a clue, then original answer is intended (before removing the zero).
D after a number means "Down" and R means "Right"
2D - 1R + 6R + 9R + 10R
3D - 10R / 4
4D - A prime power
5D - (4D x 8R) / 7D
7D - A factorial
