Free Card Combo Probability Tools

While designing our games, we needed to answer a simple question: what are the odds of drawing this card combo?

We searched online and couldn’t find anything that did just that. So we built it: upload a CSV of your deck, and get the probabilities back. That’s it.

Your data stays yours

• Nothing you upload is saved.
• Nothing the tool generates is stored.
• If you want to keep your results for further study, export them before you leave.

Two extras

We also added a Sequence Test (odds of ordered draws) and a Stack Test (odds of exact top-of-deck arrangements after a shuffle). We don’t use them much ourselves yet, but someone out there might need them. Have fun.

All three live on the Tools page.
