I had pondered on what type of game to build and came up with an idea, although it is not refined to the specifics, here are the basic.

A game with Questions and option answers from different subjects,

the first screen shows three different age brackets (5-8; 8-11; 11-15),

each of the age brackets have different topics to choose from (Mathematics; English; Colors; General Computer Knowledge; General History)

Each Subject will be in different stages, based on the difficulty and example of difficulty in stages could be:

-the first stage: click the right answer and earn points, pick the wrong option and it moves to the next stage without losing points;

-further stages have the answers moving faster and or if the wrong answer is picked points are deducted (the option motion help kids with using the mouse)

The game can start with slower moving options and can then proceed with point deductions with wrong option chosen, then faster moving options, then reduced timed duration to pick an answer [for different subjects].
