ooof, sudoku is one of the worst things to develop tetris effect for, i need to mix it up with other nikoli puzzles
i just want to email ceo -at- nikoli.com and beg them to release some of their puzzles as ebooks, they wouldn't even have to localize them for english speakers for me to throw money at them for it
- nurikabe (i love to build a wall)
- hashiwokakero (let's build bridges!!!)
- kakuro (addition crosswords)
- akari (minesweeper with light bulbs)
- sudoku (sorry bud :/)
these are just the five i've tried so far (really excited to try slitherlink and yajilin in particular), and i've only done easy versions of these (especially hashi and akari) so i may have different feelings once i start needing more advanced strats
