I built 21 Marbles for my 7-year old son because although he is generally comfortable with math, I noticed he kept getting slowed down because of forgetting basic arithmetic facts. (He obviously inherited my memory.) He was already summing 15-digit numbers, but kept getting slowed down because of forgetting whether it was 6+3 that was 10 or 7+4, or maybe 6+2. (Counting fingers while holding a pen looks very uncomfortable.) Together we thought of a game that would practice these basic arithmetic facts and be fun and challenging at the same time. His wish was for it to be on a grid. Here are some features: - This game starts out easy, but quickly picks up in difficulty. To collect all 21 marbles some brain stretching and patient strategising will be required. - It's fun to roll the marbles with real physics, break them and put them back together. - It's a sudoku-like puzzle that is quick and colourful. You won't fall asleep solving it. - It's designed for kids but is known to be enjoyed by adults. - 21 Marbles is a great opportunity to play together with children or challenge each other. - With your help or without it, this game will teach kids about looking ahead and reasoning, while also enforcing the most important addition facts for the youngest ones. - 21 Marbles is appropriate also for a school setting as it doesn't include unwanted distractions and has a very explicit and friendly measure of progress. (e.g. "Have you got a transparent marble yet?") - Features attractive marbles that motivate kids to continue even when the going gets tough. - The levels are different every time you play, so while the game can be completed in a few days, it can be played again and again and never gets old (however see the next point). - The game has an ending and doesn't try to get you or your child hooked forever. No addiction techniques whatsoever are employed. This is the first promotional game in a longish series of games that I have taking shape in my head (and at least one already on my computer). The second game is about the times table (hold on to your hats!). Not because I'm a fan of learning multiplication facts by heart (did I mention I have horrible memory?), but because I hear many kids find it hard and boring. The Balconia Math series is meant to keep math interesting for kids. They are all (I really mean 100%) interested in the beginning and then they drop out of the wagon thanks to repetitive uninspired exercises. Most math games just extend that failing model - math and play are kept separate with an abrupt question-reward divide. I aim for my games to incorporate mathematical thinking and even arithmetic seamlessly into the game's objectives.
