Found something interesting today… it’s about puzzles. But before we go into it, let’s talk something related with it first.

If you are born in the eighties or earlier, I’m sure you have piggy bank or similar when you were a kid. We have all types of piggy bank… some looks like piglet… some like rooster… some just a simple metal box with small opening for inserting coins… or if you are living in the kampong, they are more creative… they have bamboo piggy bank… a real bamboo.

With the piggy bank, we put coins into it… every time we have extra coins, we put some into it till the piggy bank full with coins. And when it is full, we simple break it and deposit the coins into the commercial bank. But there are times when we need to get some coins from the piggy bank… you know when times are hard, so we need to ‘withdraw’ some… how to withdraw?… We usually put the piggy bank up-side-down where the small opening is and shake it till the coin drops… that’s how we withdraw coins from it.

But at the same time, the piggy bank coins can be stolen the same way we withdraw from it… and this is what this posting about. I found this cool video about money maze… it’s a bank-notes bank, not coins… you deposit bank-notes into it. To withdraw the money, you need to solve a challenging puzzle by maneuvering a steel ball through the maze… watch the video…
