The Line Sudoku pack focuses on puzzles with one or more line constraints: Renban, German Whispers, Palindromes, Region Sum and Ten Lines. It includes puzzles by Phistomefel, Qodec, Clover, zetamath, Jay Dyer, Tallcat, Mr Menace, Peter Veenis, Joseph Nehme, Richard Stolk, Prasanna Seshadri, Tyrgannus, and Full Deck & Missing A Few Cards. Mark and Simon have written educational hints for the challenging puzzles.

The Domino Sudoku pack uses X's, V's, white dots and black dots placed between grid cells. Each puzzle features one or more of these domino types: an X means the two digits sum to 10, a V means they sum to 5, a white dot means they are consecutive, and a black dot means they are in a 1:2 ratio, with one digit double the other. The pack includes puzzles by Christoph Seeliger, Sam Cappleman-Lynes, Richard Stolk, Prasanna Seshadri, Phistomefel, Qodec, Clover and jovi_al, along with educational hints by Mark and Simon. Studio Goya has also curated 10 generated beginner puzzles.
