Stretch goals are an additional funding target set by the project creator beyond the original Kickstarter goal. They are there to "stretch" beyond the initial, official goal of our project and raise more money so we can improve the game further.
If you back the game and we surpass the stretch goal target, you get that stretch goal added to your pledge for free!
For example, upgraded cards is our first stretch goal at £18.5K. If you back the game at £29 and we then go on to hit £18.5K funding, we upgrade the cards in all the games, including yours!
You can find our what our stretch goals are on the main campaign page if you scroll down the page.
