The player is a ball. There are many random numbers in the road. You must take those numbers which can complete your target point. You will find plus, minus and multiplication from the birds. Remember: 1. You need to complete exact target point. 2. Point cannot be less than 0. 3. The left two numbers will be calculated by plus, minus or multiplication. 4. Right number is the collected point. 5. Don't go outside the track. Move your ball and control your brain. Be caution, there are spiders. Enjoy !
