Big win, assuming you're taking about some really big wins possibility (50Kx+) with high volatility:
If you're willing to spend 2Kx+ for bonus buy:
San Quentin 2, Tombstone Rip, Tombstone Slaughter, Mental 2.
Tombstone Rip have 97%+ RTP if you're buying the super bonus. Other three only slightly above 96%
Otherwise:
Money Train 2 (98% RTP for bonus buy, overall very good choice), Dead or Alive 2 (96.80%)
