Another mobile game I enjoy -
Tangram.
It has well over 1000 puzzles. Several are the same Daedalian Opus ones I played on gameboy years ago, after ~ puzzle 850 I still challenge these puzzles as they are increasingly complex - much more so than Daedalian Opus could provide. In addition that Tangram I'm currently stuck on
Hexagon Unlim and
Hexxagon boards (among others).
Gameboy mono does have some great puzzle games, both mono and GBC colour from cartridge and an incredible number of fan/homebrew programed games. I spent a lot of time trying a large majority of the homebrew scenes puzzle games and can tell you that I never found another like DA on this particular system. Give feedback if you want to be bombarded with other puzzle games that we like on any game system we like.
Of if you want the closest other suggestions that are kinda like to your game "DA" on other systems.
Case closed, or expanding horizons? I already got a great DOS suggestion.
...went ot - my fault.
