Designed to keep you playing not to mimic a real game
Would be a lot funnier if the app didn’t try to even the game out. If you’re up by too much the app will assign you multiple double tiles to give the other player a chance. It happens almost every game — sometimes to my advantage, sometimes to my disadvantage — I get what they’re trying to do (create suspense, increase the time you’re playing). But ultimately it’s what made me stop playing. It’s way too obvious. Assign the tiles at random!
