Pokemon battler Rumble Rush coming soon to iPhone

A new free-to-play Pokemon game, "Rumble Rush," should soon launch for iPhones, carrying over the "Rumble" series previously hosted on Nintendo's Wii, Wii U, and 3DS.

The news was made official through an announcement in Japan, according to Eurogamer. While the iOS game is only mentioned as "coming soon," an Android version is already available on Google Play.

Nintendo teased a "Rumble" game for smartphones in 2017 under the title "Pokeland," but went quiet about it until Wednesday's release in Australia on Android.

In "Rumble Rush," players guide their Pokemon across a series of islands to battle rivals and collect still more Pokemon. Clearing stages wins "ore," which can be refined into "power" and "summon" gears usable for upgrades.

Like many so-called "free-to-play" games, "Rumble Rush" incorporates ads and in-game purchases. On Android those purchases can cost anywhere between 99 cents and $24.99.
