Hasen-Hosen is an educational word game played with a set of cards; each card shows a word with one letter (a vowel) missing. Each word can be completed in several ways (e.g. H?sen can be completed by inserting either an 'a' or an 'o'). The game is played in rounds. Eight cards are drawn and placed face-up on the table. Each round, a die showing the different vowels is rolled. Then, all players try to find a card in which the rolled vowel can be inserted to form a correct word.
