Combine numbers and Make 10! Move numbers to the ring to make ten. Enough successive combinations will advance you to the next stage. See the top left screen to see the number you need to make; this number increases after you successfully make it several times. If you can't make the number, the bottom bar moves. When you have at least 5 required numbers side by side, you can make a row and reduce the bottom bar. Playlot more math games only on y8.com
