Top 10 Ideas for Saw Traps
10 people are on a spinning platform. Someone will land in front of the chainsaw. The guy(protagonist) can either press the green or red button. Green: Chainsaw cuts down the rope around their necks, but his hand gets shot. Red: Chainsaw slashes the victim. However, he can only save 4 out of 10 people!
The straps around the 4 victims have wires that connect to the other end of the room which has fire. They have 2 minutes. Every 30 seconds, they are pulled closer. They're separated by glass. One person has buttons in their section, which they have to push to release all of the straps.
One guy must find tools to slam the locks on the devices, which are on the other 3 victims(each of the 3 has 5 flesh grabbers on them). However, he has one on him as well.
Key in the middle of the circle. Spikes underneath the circle for the people who fail to get out of the room in time.
