Dead Simple Lock & Trap Mini-game. This was created with help from - oh - just about everybody in the community. I must say, it's working great. The Boy is loving it. Whenever there is a lock or trap, I start shuffling the deck of cards and he runs around the table and stands next to me, making his guesses and wanting to see the cards first hand as I reveal them.
The other players seem to enjoy watching - but I was surprised that one player reported using the mini-game in the rpgs he runs as well. He said he used it for Pathfinder and it was a hit. But even more surprising, he started using it in his Shadowrun flavored Savage Worlds games as well, to handle cyber-intrusion. Seems like it works good for any time you need to create a little more tension than just a flat die-roll, but not take too long.
One little problem I have is that the Boy tends to do a bit better than he should statistically. Whether he is psychic or not is up in the air, but I'd say that the chance that he is reading his old man's unconscious cues is much more likely. :)
I'm impressed how fun the simple little thing is. Go ahead - give it a whirl. It won't bite.
