The Frozen Lake Station
A blizzard has sealed your team inside a research station on the shore of a frozen Arctic lake.
Patterns · Petri dishes · Dice · Logic clues · Symbol gridEach lock has four multiple-choice questions. A team answers all four, then uses that lock's decoder to turn their letters into a four-digit combination. One wrong answer makes one wrong digit, so the lock stays shut until every answer is right.
Play online from a link, checked as they go, or print the pack on A4: question cards, decoder cards, a record sheet, the teacher guide and the answer key.
Tick what your class has covered. The room takes 20 multiple-choice questions from the site's checked bank: one per family, so no question gives another away, the harder ones at locks 4 and 5, and no figures. You can edit or swap any question afterwards.

Locks 1 to 3 test the facts, locks 4 and 5 apply them. Playing online needs no account; the teacher pack, with every answer and combination, opens once you sign in. Edit a copy to make a room your own: change any question, decoder or difficulty, and your class plays your version from its own link.
