This sticker mod is for those who play or, at least, know the basics of Sudoku, and more specificaly, the "Killer" variantion of the puzzle.
Each face of the cube, in solved state, must have the numbers from 1 to 9; and being an adaptation of the "Killer" variant, there are some tiles that have an arrow with a little number; the little number tells the sum of all 3 numbers on a row (if the arrow points to left and/or right) or in a column (if the arrow points upwards and/or downwards).
Unlike other sticker mods that you can find all over the internet, mine are available only in a "scrambled" state, to make things more challenging. If needed, send me an e-mail and I'll send you a step-by-step solution of the Killer SudoCube.
You can download the files in three formats: in PDF, CDR and SVG. The CDR files can be edited in Corel Draw 2017 and newer; SVG files are meant to be edited with the free software Inkscape (recomended).
I suggest sending the files to a printing store, to print them on self-adhesive vinyl, preferably already cut to peel and stick (it's cheap and fast, and the result is great (I use this method, see photos of the results here).
Enjoy!
(I will provide the downloadable files soon - site in construction, sorry)
