HAPPYHALLOWEEN is worth 775 Robux
One level costs 25 Robux in the shop, so 31 free levels would cost 775 Robux. HAPPYHALLOWEEN only works after you have played for 31 minutes, and NOLIMITTOTHELARVA after 30, so redeem them near the end of a game.
Two more may still work, so give them a try too. Type Rose with a capital R first, and if that does not work, try ROSE in all capitals.
