I just happened to notice the blue glass counters at the dollar store, and I thought they'd be nice to play this game with, but that meant that I had to find something to use as a board. I spotted some cheap ice cube trays on another aisle, but the problem with that was that it would make a game with too many pits! I ended up sawing an ice cube tray in half with the miniature saw on my keychain multi-tool, which I don't particularly recommend--it was quite a lot of work for what I was trying to achieve. Anyway, once I had cut out the center two compartments, I managed to glue the pieces back together--the underside of the join is strengthened with scraps of plastic from the section I had removed. Oh, and lots of good, strong glue. The large scoring pits are made from yogurt containers I had been keeping with my craft supplies. It turned out to be good that those aren't attached, since we can easily swap the ice cube tray with an uncut one for a variation of the game.
While I don't recommend sawing ice cube trays with miniature tools, I do recommend the game mancala. It can be inexpensive to buy, if you can find it; I used to have a purchased set that cost about two dollars, which is what I paid for a bag of glass counters and a pair of ice cube trays. The last time I looked for it in stores, though, I couldn't find it. You can also make a board out of an egg carton, but I chose the ice cube tray because I wanted it to last longer. Almost any small item, such as dry beans, would work for the stones, if you want to try it out with stuff that you have lying around and aren't sure that you need a permanent set. Everyone I've ever seen play it was hooked after a game or two, though!
