A2–B1 prepositions cases grammar offline
Prep the Deck
A card game that finally makes dative and accusative click.
Prep the Deck is a German card game in the style of UNO, played against the computer. Every card carries a preposition and a short sentence with a gap, and to play it you pick the right article. Empty your hand first to win. It is the fun way to finally get a feel for which preposition takes dative and which takes accusative - including the tricky ones that can go both ways.
The most useful prepositions in German and the case each one takes - plus the article that goes with it. Instead of memorizing a table, you make the choice again and again inside real little sentences, which is what turns the rule into an instinct.
Like UNO. You play a card that matches the one on the pile, either by preposition or by case, and to put it down you choose the correct article for its sentence. First one with an empty hand wins.
Some prepositions take dative when you describe where something is, and accusative when you describe movement toward something. The game gives you both versions of a sentence and lets you decide - which is exactly the decision that trips learners up in conversation.
A2 to B1. You should know der, die and das and recognise simple sentences. If cases still feel like guesswork, this is a good place to fix that.
Turn on the tip and the game narrows the choices and names the case, so you can reason your way through instead of guessing blindly. Wrong answers only cost you a turn - nothing else.
