Queablo

This game combines a word game with mental arithmetic: In each round, a magical number is determined with a dice. Open displayed cards show one consonant and one number at a time. Players try to build words with the open cards completed with some vocals. While searching for matching words, they always have to check the cross sum of the used numbers which must match the magical number. The game comes together with 3 variants. More can be found on the official website.
