The Number Birds come and go on the telephone line. Click a bird to add its number to the running total. There's no time limit in this game but you still have to be careful as you don't want to go over the Goal Number.
Click or tap the Number Birds to add their number to the running total. Reach the Goal Number without going over. Once you get the target sum you'll be given a new number to reach. You'll get more moves each time you reach the Goal Number without going over. The game ends when you run out of moves or go over the Goal Number.
