The HotPotatoes test set consists of six programs: five basic test tools (JQuiz, JMatch, JMix, JCloze, JCross) and one tool called Masher that combines the different tests into test units. HotPotatoes allows teachers to create interactive multiple-choice, short-answer, jumbled sentence, crossword, matching, and gap-fill exercises for online use. While free for educational institutions, the Masher program requires payment to combine exercises into cohesive units.
