けいさんかけっこ

If you answer the calculation problem on the screen correctly, the penguins will run cutely toward the goal.
If you answer correctly quickly and continuously, the speed will increase.
Animals (friends) support the running penguins.
The level will increase according to the number of problems solved, and the number of friends will increase according to the level.
The best time is recorded for each problem category (addition without carry, addition with carry, multiplication table, etc.).
Let's do our best to complete the friends (currently 31 types) and update the new best time!
For first and second graders of elementary school. Free.
