To get an extra Gollum token once a day, press the 'Share' icon at the bottom of the page and click 'email'. When prompted whether you want email or gmail, select 'gmail'. You will then be taken to your message drafts in your email where you should then click the 'Save to Drafts' option. This will then take you back to the screen you arrived at after you selected the 'Share' icon. Repeat this process 10 times to get the extra token.
Save up Gollum's Tokens and use them on 'Premium Chance' to collect better prizes. This requires 6 tokens to play but you can cut the wait to 3 days instead of 6 days by getting the free extra token available daily. There is also a chance while playing 'Premium Chance' where you could win some hobbit building crews or training runes which can be used to level your hero.
While scrolling through map view you may notice some bubbled cities. These are cities of players that are still under protection (cannot be attacked). To 'pop' some of those bubbles, specifically those which are over 5 days old but inactive, do the following. Write down/bookmark coordinates for that bubbled city, then go to your Muster Field and input the coordinates manually or pick them from the bookmark list. Once done, select your hero and assign him some troops. Then attack that target. NOTE: Not all the bubbled cities can be popped. You can also try this for players who are using protection runes.
