Hopefully you enjoyed this video, i figured i would upload my oll algorithms because ive. If youre using my beginner method, it takes you one look to orient edges, up to three looks to orient corners, up to two looks to permute edges, and up to three looks to permute corners. Easy cases 14 u r u r use r f r f if no u face edges are. These algorithms are all taken straight from my full oll. This reduces the amount of oll algorithms required to memorize from 57 to 7. I have chosen these ones because they heavily use three different triggers, which i feel allows for easier memorisation. Losungsanleitungen zum ausdrucken speedcubing schweiz.
