The full Frequency Disappearing Ink bundles includes PART 1 and PART 2. This pack features 200 4x4 and 5x5 puzzles and well, it got pretty tedious to input all those numbers, so I may have left some out….you’ll be fine, right? Disappearing Ink increases the difficulty of the puzzles without increasing the size, demanding more logic without demanding more arithmetic. Try out this new twist!
