I have incorporated this game for business English participants with positive resonance. It does take a longer time to play; over an hour, as players tend to win cards and then lose them in the process of trying to fulfill a "win". Each card offers the option of five different levels in the areas of vocabulary, grammar, phrases, and general knowledge of area called "This and That" (this area includes Numbers & Symbols, Dates & Times, pronunciation, American or British English spelling, etc.)
What is helpful is indeed the directions on the cards are written in English with German translation Both. There is an addition Rules Guide therefore provided in German for Further clarity for non-native English learners.
This standard British English card game players from ages 2-16 Suggests 12 years and up are suggested. I used this game in business English courses. The participants really enjoyed playing.
