14 Minesweeper Variants Episode 15 - Trying to Unlock Some [+'] Variants

So I finish the last [+]8x8 board, but then to unlock any [+'] variants I need to complete three 8x8 boards of the two variants it is a combination of. I manage to complete 3 with Triplet, then work on doing so with Quad and manage to unlock 8x8 but not complete any boards with it.
