About To Build a Better Mousetrap

Have you ever wanted to play mad scientist and engineer a contraption that could trap a mouse? That’s basically the whole point of To Build a Better Mousetrap—except instead of real mice and real danger, you’ve got colorful cardboard ramps, plastic gears, little metal balls and a handful of dice. You start each round by drawing a blueprint card that lays out the basic steps your contraption needs to follow. Then you dive into the pile of pieces, fitting ramps to levers, attaching pulleys, balancing beams—whatever you need to make that little metal mouse roll just where you want it.

Once everyone’s slapped together their ideas and set the last tiny hook in place, it’s time to see if your design holds up. You take turns rolling dice, moving the mouse along the path you’ve built. If the dice cooperate and your trap springs shut, you score points and earn bragging rights. If not, you get to laugh at how gloriously it backfired—and scramble to rebuild or tweak your plan for the next go. There’s a real thrill in watching what you’ve cobbled together perform—or spectacularly collapse—in a single clatter of tumbling parts.

It’s a game that thrives on trial and error, so while there’s a bit of strategy in choosing which pieces to use, most of the fun comes from the unexpected chain reactions. Families love it because kids get hands-on with problem solving, and adults can’t help but grin when their grand design spontaneously unravels. By the end of the night you’ll have stories of spectacular failures, narrow escapes, and that one perfect trial when the trap did exactly what it was supposed to do—and you’ll already be scheming about how to build an even crazier one next time.
