It’s name began with D and I think it was a two word named game who’s second name was also D.
The object was to get rid of like blocks (like mahjong) but the blocks had to be situated such that no more than two straight lines could be drawn between them.
It’s a game, along with bejewelled, that I played a lot like 5 or 6 years ago.
I don’t know of the specific title you’re looking for, but I’ve played games with the same rules under a variety of names. Sports Match as an arcade game, the Rivers game selection of the Kyodai shareware release, Four Rivers online.
Edited to add-- the game wouldn’t have been “Dragon Punch,” would it? It’s an arcade game of which Sports Match is an American variant; DP uses mahjongg tiles rather than sports-themed graphics, and has a hentai “reward” for solving each level.
As far as I can remember how it went, the link game is pretty much the same. The original game had square (not rectangle) tiles and many more of them. The overall colour scheme was darker (black or dark background behind the tiles, and a visible timer (bar getting shorter or longer)
But I can play the above game for now as it’s almost exactly what I was looking for.
