Plutoku: A Pleasing Riff On Sudoku

I demand fiendishness

Here’s a tiny puzzle game which riffs on the principles of sudoku puzzles. It’s called Plutoku and was made by a group of students for a class.

The idea is familiar – you need to fill each row and column with one of each number block (or colour block if you prefer). To add them to the board you click on them as they float past and they will “drop” into the board until they either hit another block or the far side of the board.

The first levels are incredibly easy, particularly if you know that diagonal lines don’t conform to the “one of each kind” rule but later levels are more interesting, requiring a degree of logical thought, both in terms of knowing which blocks are needed and adding them in the right order so as not to block access for other blocks.

I do often do sudoku – they’re really useful for when I can’t sleep – and I think this riff on the basic idea is neat. It’s the sort of thing I’d really like to see developed further and made horrifically difficultr.

    Ooh, that was interesting. My favorite riff on sudoku remains mathdoku, but that was a great spin on it. I feel like I leveled up my sudoku ability by looking at it form the perspective of the sudoku maker.

    Pretty nice. It solves my main gripe with sudoku, which is that it’s pretty much solved. Adding movement restrictions solves it.

    I used a lot of ‘solve’ in this post. Perhaps playing that game filled me with an urge to put a lot of similar things side by side.

    An interesting idea, but the controls are awful. Trying 85 times to get something to slide into the slot is not fun.

    I did too many magic squares in my discrete maths subject last semester for 3×3 and 4×4 to challenge, but I liked the little slide-puzzle touch nonetheless.
