Jenga is probably one of those board games that works well due to its simplicity, like Battleship. Of course, I have seen Battleship done up when it shouldn’t have, like that movie they did last summer.
You might ask why Jenga should be improved. Perhaps it shouldn’t be. I believe there is a line from The Simpsons Game where the Comic Book Guy says: “Is your game boring? Just add a clock!”
In the case of Jenga, you can improve it with Jenga Boom, which has a ticking time bomb base that will topple the tower once the timer runs out.
This is pretty cool, and it will only cost you about $18.00, but I have no idea if batteries are required.
