Talking about Supercell, I will definitely remember the phenomenal game Clash of Clans. In its heyday, almost everyone who owned or had just bought a smartphone must have installed a game that makes you keep opening it, either just checking the gold or elixir collected to prepare troops for clan war.
After success with Clash of Clans, Supercell re-launched a game that could be considered a spin-off from CoC with a touch of gameplay card game titled Clash Royale. Each card game is also adapted from CoC characters so you will see characters that are not so strange, even when playing it doesn't take too long to adapt.
Still regarding Supercell, recently they turned out to have prepared a new game called Rush Wars. At first glance, this one new game is like a combination of gameplay from Clash of Clans and Clash Royale which are combined into one unique game.
The gameplay concept of this game players must prepare decks in the form of troops to attack enemy bases to get resources such as gold. In addition, players also build defense headquarters to support resources such as gold mines to several other buildings.
Supercell itself has released a soft-launch for Android and iOS in 3 countries, such as Australia, Canada and New Zealand. It is still unknown when they will release globally, if you see the trailer of the Rush Wars game is quite interesting to wait for its release.
