While HoFa has a lot of pages that are easily findable through dropdowns, there are also a handful of pages that don't appear here. You can find out more about those below (page names are hyperlinked).
The Official Wiki is also a maze of pages, the best thing I can recommend for the wiki is using the search feature to try and find related pages since some wiki pages are hidden or insanely hard to find.
By clicking on "Estate" itself you can find your Estate Overview page. This has some information like pathway income, horses that retired during the most recent rollover, horses that grew up from foal to adult during the most recent rollover, and recent notable show placements.
By clicking on "Town" itself you can find the Town Map and all related buildings. In the list you can find Game Room and go earn an extra small stash of bits.
More games and an overhaul potentially coming soon....
By clicking "Community" or "Forums" players can find the Shouts button on the top right of the page (its blue). These can be used as advertisements on the site for those who do not have them turned off (an account setting). Players can have 3 shouts active at one time, and making one has a 100 bit fee.
By clicking on "Market" itself you can find the Market Map and all related buildings. In the list you can find Bank. You can also access your bank by clicking on your current bit amount. The bank is where you can move and see money in hand vs in the bank and access your bit related transaction history. Money placed into the bank will earn interest every Sunday during Saturday -> Sunday night rollover
By clicking on "Market" itself you can find the Market Map and all related buildings. In the list you can find Ingot Store. You can also access the ingot store by clicking on your current ingot amount. The ingot store is where you can buy ingots, campaign coins, item packages / bundles, subscribe to the game, buy ingot based account upgrades, view purchase history and ingot related transaction history.
You can view your own player profile by either clicking your name or clicking on "Account". From here you can view your active Boosts, general information, and your profile description. To edit this page head to "Account" and then "Settings"
