It has a button that deactivates all of the other buttons after a game has been selected. This keeps an errant dart or one that bounces off the board funny from resetting the game you are playing. There is a pretty resounding thump when a dart hits the board. Like many other machines, doubles that land outside of the scoring area may register as a double. I'm betting that 3 out of every 4 darts that I have hit the double bull with have ended up on the floor.
Darts seem to stick in the rest of the board without any problems.
Even though they may not stick, the machine still count the double bull as being hit. Every once in awhile the machine has counted 1 dart thrown as 2. The sad part is it always just seems to happen to me. The single bull is always worth 25 points and the double bull is always worth 50 point in both cricket and '01. It comes with 8 sets of darts.
