It takes 100,000 base points to become a Seven Stars guest. It takes roughly $5 through a slot machine ($10 video poker) to earn one base point. So you will have to run $500,000 through a slot machine to become Seven Stars. At most Caesars properties the machines hold around 10% give or take. So you will have theoretically spent $50,000 just to get to Seven Stars level. Most Seven Stars are way higher than just the minimum threshold.

On a penny machine with 20 lines (I just picked a simple number) at 5X coin in $1 per spin. At 10 spins a minute (once every 6 seconds, a reasonable amount of time). It will take you roughly 104 days playing 8 hours a day. But if you up the denomination, the coin per line, and the number of lines you could shorten that time to become a Seven Stars.
