However, there is always an edge to the house to make sure it does not go broke, but simply saying "you'll lose the longer you play" is a lie.
It is not a lie actually it is a fact, regardless of the house edge, since the game is a game of chance, the times you roll will increase both the losing and winning chance but decrease the chance to have a streak of winning. the difficulty is raised exponentially, you can apply a series of flipping a coin and the odds that it will be landing in series of same side will decrease. To the calculation, saying we flip the coin six times, the odds will be 1/2 ^ 6 which is 1/128 to have a 6 straight landing of the same side.
That may be true. However we are not basing this on whether you'll win several times in a row, we are looking at if you can gain profit in the long run.
If you've ever played casino games you'll know that you don't only win your initial bet back, you usually win at least 2-5x the amount. So, we do not have to win several bets in a row to stay in the profitzone. You see?
That is why it is not a fact that you WILL lose in the long run, because it is random. The game does not have a memory, each beat you make is made on a fresh string without attachment to the previous bet.
