The first expansion for Stak Bots is now on Kickstarter:
Stak Bots is a fun, simple and sneakily strategic battling card game suitable for all ages.Link: Campaign on Kickstarter
It is quick to learn but it will grow with you; as you get more competent you can add more Staks, more rules and more Bots. To start with there is a lot of confusion and luck, but once you become more aware of what each Bot is capable of and what the likely consequences are of each action, you'll find that sneaky little strategies become apparent and that luck can often be managed and even planned for. After playing thousands of games, I am still encountering new situations and combinations.
