Players take turns playing cards that add to a running total. Push it past 99 and you lose a token. Lose all three and you're out. Last player standing wins. Special cards change everything. Reverse direction. Skip the next player. Slam the total to 99. Reset it to zero. Every card is a decision — play it now or save it for survival?
