Be warned: sometimes the machine can give you characters you've already unlocked, so it's not necessarily as easy as using it x amount of times to unlock all of them ! This is another factor of the game which makes it addictive, as you have to play it for a long time and collect an awful lot of coins in order to finally collect all of the different characters. Free coin gifts are offered by the game at timed intervals, starting every few minutes and progressing to every few hours, and once you have collected enough coins (100) you can use them in the vending machine (see below) which will then give you a box containing a character. and usually appear in more 'difficult' locations to reach, meaning that they are both challenging to get and rewarding to collect. These can appear anywhere throughout the game - on floating logs, in the roads, on the grass, on the railway lines etc.

One of the key features of the game is that you can unlock more playable characters using the in-game currency you collect: small, bright yellow coins with a 'c' in their centre.
