Quadrapassel imachokera ku masewera a caltic-block, tetris. Cholinga cha masewerawa ndikupanga mizere yathunthu yopingasa, yomwe itha. Mabatani omwe amabwera m'magawo asanu ndi awiri osiyana omwe amapangidwa kuchokera ku mababu anayi iliyonse: imodzi yowongoka, yowoneka bwino, lalikulu, lalikulu lalikulu, ndi mawonekedwe awiri. Mabowo amagwa kuchokera pakati pa chinsalu mwadongosolo. Mumazungulira mabatani ndikuwasunthira pazenera kuti muwaponyere m'mizere yathunthu. Mumalemba potsitsa mizere yofulumira komanso yomaliza. Pamene gawo lanu limakwera kwambiri, mumakhala ndi malire ndipo mabatani amagwa mwachangu.
