Order by the year each boxer first won a world heavyweight title. You place all 40 cards on one timeline, one at a time. You start with three lives, and ten right in a row wins a lost one back.
Each card names a boxer who held a world heavyweight title, and they go in order of the year he first won one. His nationality and nickname are printed under the name. The opening card is already down with its year showing. For every fighter after that, choose a gap among the champions placed so far. A good call puts the year on show; a bad one still moves him to his real spot and costs a life. You have three, and ten correct placements in a row earn a lost one back.
The lineage reaches from the first gloved champions to the fragmented era of rival sanctioning bodies, when the title could change hands several times in quick succession. Only a fighter's first title counts, so a great who regained the crown much later is placed by his first reign. Nicknames are fun but rarely date anyone. The hardest champions to place are the short reigns squeezed between long ones, and the brothers.
