I could write one if you want. The turns are briefly explained in the source. Here's how it works:
- For Triplex, the three faces are R, U, and F (although L turns also work for the F face), and turns are the same as on the hi-games sim. Specifically, i/k for R, j/f for U, h/g for F, and d/e for L.
- For both Quadplex versions, the four faces are R, U, F, and L, and turns are the same as on the hi-games sim.
- Space scrambles, Escape quits a solve (and clears your rolling average if you were in the middle of it).
