Playing with LONPOS brainteaser games enhances math skills, hand-eye coordination, patience, concentration, cognitive skills and self-confidence. At the same time, they are fun and even addictive. They are great fun when two or more players vie with each other to see who can finish a problem first, perhaps to win a prize.Fantastic for all ages it presents challenging problems yet is so easy to understand that supervised children from the age of 3 could have a try at some of the easier problems.
