Into yalo mdlalo ukuphatha la ma-tetromino ngenhloso yokwakha umugqa ovundlile wamabhulokhi ngaphandle kwezikhala. Lapho umugqa onjalo wenziwa, uyanyamalala, kuthi amabhlogo angenhla (uma akhona) awe. Njengoba umdlalo uqhubeka, ama-tetromino awela ngokushesha, futhi umdlalo uphela lapho isitaki samaTetromino sifinyelela phezulu enkundleni yokudlala.
