Even though Splendor Marvel uses Splendor’s core rules and high-quality materials, it has a different color structure, a new endgame trigger, and new victory conditions. You can also gain Infinity Points with the Avengers Assemble tile that can be passed from one player to another several times during the game!
If you are keen on Splendor, learning the rules will be easy, but mastering the game may take you a while.
