Albeit rare, competitors can have multiple +2 penalties in a single solve. In that case, the sum of the number of +2 penalties multiplied by 2 seconds is added to the result time (number of +2 penalties * 2 + base time = final time).
Reasons for a +2
A +2 can be given...
- if, when the timer stops, the twisty puzzle is one move from solved in OBTM, but not solved
- if the cube does not land on the mat in front of the solver after their solve is complete
- if the competitor takes more than 15 seconds but less than 17 seconds for inspection time (if inspection exceeds 17 seconds, it is a DNF)
- if the solver doesn't start the StackMat timer with their palms facing down on each side of the timer
- if the solver is touching the puzzle and starting the timer at the same time
- if the solver doesn't fully release the puzzle once they stop the timer, at the discretion of a judge (otherwise is a DNF)
- if the solver doesn't stop the timer using both hands, placed flat on the sensors with palms down
- if the solver touches the puzzle after the end of their solve and before the judge inspects it
- if a blindfold solver has physical contact with the puzzle before the start of the attempt
