“Clash of Clans,” the highest grossing app on both the Google Play Store and the Apple AppStore, released a long-awaited update on Wednesday that enables a new feature called “Clan Wars.”

“Clash of Clans” is a real-time strategy game where players build up the walls of their town, join clans and go out on raids for loot. Previously, players were only able to attack the towns of other players, but with the update, they can now go head-to-head against opponents in real-time.

Supercell, developers of “Clash of Clans,” are calling it the “biggest Clash update ever,” as players can now wage “clan-versus-clan” battles. The game’s Clan Castles, which used to  hold only small backup armies donated by members of a player’s clan, now hold the loot won in clan-versus-clan, which can be stolen by attacking armies.

Clan Castles can also now be upgraded to Level 6, to hold larger donated armies and more gold and elixir. Supercell also promises boxes of gems popping up on maps during attacks. Gems are offered to gamers on a limited basis -- they allow for shorter wait times when upgrading or building an army and are the primary driver for the app’s profitability.

Supercell charges $19.99 for 2000 gems in app stores, and also sells other items available for free in the game, including gold, primarily used to upgrade defenses, and elixir, used to build armies and upgrade offenses.

Full disclosure: I play “Clash of Clans" quite a bit. The real-time nature of Supercell’s strategy game makes it the best, most addictive mobile game available for Android and iPhones.
