Spoiler:
Do next five tasks blindfolded (tasks are anything which take more than 5 mins,so some which just give instructions may not count )
You remove the Blindfold after doing the task, re roll and prepare for the next task and wear the Blindfold again.
The following won't be considered a task but you have to do it for proceeding further:
Roll a dice while blindolded (on a app or actual), guess the outcome then remove blindfold,if what you thought is the answer go 2 spaces ahead or if wrong 4 steps back
