Pokémon Duel is totally different from Pokémon Go which combines the Pokémon franchise with what is essentially a strategy game rather similar to Go.
The game works like a figure battle game that you need a team to move across a board.
It is available for both iOS and android devices. The game is possible to finish without spending a cent. Gems can be accumulated by battling as well as logging in every day for login bonuses as well as daily missions.
