HOW DOES ENDER DEFEAT THE GIANT IN "THE GAME?''

Ender plays the "mind game" and generally does well, but the game always returns to the Giant's drink. Although he figures out that the choice is pointless, Ender keeps returning and trying to find ways to beat the Giant, because the Giant talks about a "Fairyland" that the players can go to if they beat him. Finally, Ender kicks over the two glasses, jumps into the Giant's face, and digs into the Giant's eye. Eventually, the Giant falls over dead, and Ender reaches Fairyland.

Ender does defeat the giant but i do beleive that ender keeped on trying tills he succedes but when he reilizes it dont matter which one of the drinks matter so he spills it on the giant and killes him by going in the giants eye ball to go to fairy land
