Board Game Arena

I have won 12 games in a row just by sitting on my Higher Tiles. I play my lowest tile every time. I do like the game but that one aspect breaks the game. My last game I had 4 unplayable tiles at the end of the game that all scored.

There should not be a reward for tiles not played. That doesn't make sense. I like the game but sitting on a 4-4 and scoring 8 points at game end is a disadvantage to someone who played all their tiles. Is this rule correct?
