With the end of Mochi media, a lot of flash player sites have disappeared. By running Mochi media flash games, other gaming sites could also make good money with in-game ads. With the proliferation of mobile phones and the games that can be run on them, there have been fewer and fewer people playing traditional flash games, so it was not worthwhile for the Mochi media to continue to force this business. I suspect that the 669.hu page has also fallen victim to this thing, ie the spread of the mobile game market.
