There are a few games showcased in the trailer. One is a simple game of maths where players have to show the answer to the IR camera on the right JoyCon, using their hand. Another simple counting game involves using the Joy-Con to hit the ZL / ZR button to tally up the numbers. One game that does not involve counting looks to be a Japanese character word guessing game, which is played with the Switch held vertically. https://www.youtube.com/watch?v=Tjtvl2-cpb8 A fair number of the minigames make use of features specific to the detachable Joy-Cons. Given that the Nintendo Switch Lite doesn’t have detachable Joy-Cons by default, Brain Age may not be compatible with the Switch Lite. The game is currently set to be released in Japan on 27 December, with no mention of a release in other regions. The game will cost JPY3480 (~RM135) for a physical copy that comes with a stylus, while the digital version will cost JPY2680 (~RM103). (Source: Nintendo via The Verge, Engadget // Images: Nintendo)
