I, too, have not had that experience.

It appears under Winning the Game

To win the game, a player needs to place all tiles in the hand to the board. As soon as someone manages to do this, the game is over and this player is a winner. Placement of the remaining players is decided by the value of tiles left in their hands - each numbered card incurs as many penalty points as its number is, while Jokers incur 30 penalty points.

If the pool runs out of tiles, players can pass their turn instead of playing tiles on the board. If all the active players have passed their turn in sequence, the game ends in a draw.

I will make that proposal.
