Endless

Expert tier
The hardest settings of the Play & Learn games, pulled out for grown-ups. Every one opens on its own level picker: choose the Expert tier and the margins get thin. They are still in Kids Games too.
🏆
Champions Duel
459 finals across eight competitions. Name the winner, then the year, the score or the margin. Harder than it sounds once the 1970s come up.
🏛️
Who's the Boss?
201 current heads of state and government. Name the country from the leader, then name the job. Most people find out here that they know about twenty.
⚾
Ball or Strike?
Call the zone in the Replay booth, where the ball misses by under two units. The zone is sized to the batter, so the same pitch is a strike to one hitter and a ball to the next.
🏈
Catch or No Catch?
Two feet, control, the football move, surviving the ground, and the sideline to within a unit. The rule that decides it is the second question every time.
🚩
Offside or Onside?
VAR review margins: three units, not forty. Then name the law behind the call, including the ones most fans get wrong about throw-ins and the second-last defender.
🏏
How's That?
Third umpire mode. Bowled, caught behind, LBW, inside edge, no-ball and stumped, with the tracking shaving leg stump and umpire's call in play.
📊
Is This Chart Being Fair?
The Expert tier is a data-literacy test: truncated axes, uneven year spacing, picture bars scaled in two dimensions. Each one redraws honestly after your answer.
🎖️
Champion Challenge
The decathlon. Sixteen rounds drawn from the hard half of six games: set logic, ratios, deduction, verbal reasoning and geography, back to back.
