Preterite vs imperfect

Fui or era, tuve or tenía: the two past tenses side by side, then a game that mixes them.

Choosing between the pretérito perfecto simple and the imperfecto is a grammar question, but getting the form wrong is what gives you away. Both tenses sit at A2, and the irregular preterites (fui, tuve, hice, pude) have to be memorised.

The game shows one form and asks whether it belongs to the tense on the card. With exactly these two tenses selected, every wrong form comes from the other one, which is the confusion you want to train.
