100,000K

Score 100,000,000 in a single hand - a proper break-the-game number. You need a snowballing multiplicative engine: scaling Jokers (ones that grow each round) plus ×mult Jokers plus a highly-levelled hand, ideally deep into a strong run where you've had time to build. Retrigger and multiply everything, then dump it on one hand. The flashy chase-the-numbers achievement.
