You have some word, that you're spelling out, and there are letters to the word that are collected. Then there is either a positive or negative reward.
In many pinball games, you have to hit each of a sequence of letters, spelling some word in the theme of the game. You get some sort of reward when you get them all.
In video games, a level frequently features the letters of a word, hidden in various places. You collect all the letters, and get some sort of reward.
In "Horse," a game played with basketball equipment, players take turns throwing hoops. For each successful throw, you get a letter: "H", "O", "R", "S", or "E". You can only get them in sequence, though, so it's not really about collecting letters.
Related but Different: ?HangMan, ?BasketBall, and the ?WheelOfFortune, all of which prominantly feature letters.
