What Can I Use My Syns On?

You can use your Syns on absolutely anything. It doesn’t matter how unhealthy it is, so long as you only use 15 Syns for the whole day.

You can use them to add extras to a meal for more flavours or use them for a more fulfilling snack such as chocolate. You could even do both if you choose how you use your Syns wisely. I prefer to simply save most of my Syns for the evening and have a few treats or some alcohol.
