Pokéland is currently undergoing a new round of alpha testing for Android devices in Japan effective 17 October 2017 until 27 October 2017. Only approximately 30,000 players will be able to take part as long as they have access to the Japanese version.
We previously reported the first round of testing which took place earlier in 2017, with new features and locales for the latest version. To recap on the gameplay, progressing through the battle will have you tapping on Pokémons to defeat them. Slide on the screen to avoid incoming damage. You are still able to collect treasure chests and P coins which serve as in-game currency.
In case you are wondering, there will be a testing phase for the iOS sometime early 2018 as well, so be sure to stay tuned. Drop by the official Pokéland website for even more details.
