Planning poker is a method used in agile development to estimate complexity of tasks. For more information see Planning poker (wikipedia).
As we could not find a good set of cards (either there were some points missing or the cards looked awful), one of us spent a Friday afternoon designing our own set. You can download it for free.
The set contains cards with points according to the Fibonacci scale (1, 2, 3, 5 and 8) plus cards for zero points (Few minutes work) and infinity (I find it too complex to do it in one day). In addition, there is one card with a question mark on one side (I honestly don’t know…) and a beer on the other side (Sorry, I was thinking of something else…). This is just one card because in both cases, there really is no reason to hide it.
