For elementary school, I have 3 games this year that I would classify as hot. For my definition of 'hottest' I employed the 'free time meter'. Meaning, English games I have seen the students playing during their free time moments during classes or after lunch.
1. Boom Boom Game -
ESP Game BoomBoomGame
2. Eto Game -
ESP Game Eto
3. Senaka Me -
Senaka is Japanese for the center of one's back. Students try to guess various letter written on their back by their teammates' back. This game is introduced by Daft Punk's
One More Time song.
