For every day you have played a game during the cycle of the Daily Rewards you will move up the tier, stopping on each level to gain your reward - you could play for 7 days, miss a few days and then do another 3 days to get your 10 Day Rewards. It's really that simple; you don't even have to play every single day, but remember the Daily Rewards will reset the 1st of each month!
While Tax Collector is in play, you gain +1 Capital whenever a creature is deployed.
