We haven't yet gotten round to rejuvenating the Puzzle Championship Series here on SoSG. However, we at SoSG World Headquarters always have plenty of time for time-wasting activity, and here's one we can join as a group to waste time collectively!
Marvel Puzzle Quest: Dark Reign is a turn-based puzzle game using the "match-3" mechanism made popular by Bejeweled and Candy Crush. However, like the highly addictive Puzzle Quest series, this game incorporates character leveling such that the puzzles are actually "battles" against computer-based AI, rewarding successful battlers by allowing one to advance one's characters ("leveling up"), making them more likely to win future battles.
What's cool about this game is, players can join alliances which allow groups of players to combine their wins towards a tournament ladder of sorts. There are multiple ladders in play at any one time, so it makes it fun figuring out how and when to contribute toward the alliance's goal. You can contribute as much or as little as you can, but the alliance's total score at the end of the period can earn the whole team points (and you also earn individual points as well, on a separate ladder).
Currently, we've got three Sons playing in an alliance. I think the game is cross-platform, but we're playing using the iOS app (free in the app store; there are in-app purchases however, though I've gotten away with spending only $10 to date).
If you'd like to join our crew, leave a note here and/or search for the alliance called "SoSG Fest". There's a limited amount of space available, so join soon!
