Rox is the currency of Monstro City, which are colourful gems that can be earned by playing games, completing quests and puzzles (located around Monstro City).

The easiest soluation to getting Rox is to play the Daily Puzzle. According to how many right answers the player get, they are awarded around 70-130 Rox. Players  can also play the individual puzzles, and get 5 Rox for each.

Players can play these games more than once per day but only the first one gives you Rox. Other games that earn Rox are Moshling Boshling (in which you can get 30 Rox per level depending on how many cupcakes you collect), the Underground Disco, the Ice Scream Parlour, En-gen and the Flutterby Field. There is a maximum amount of Rox players can collect per day and after they reach that, these games will not give you additional Rox.

Sometimes, there are characters standing around with a yellow bubble with an exclamation sign in it; if a player talks to them, they will give you a task like finding a Moshling, taking an item to another character, or finding sapphires in the beach or Port.. When you complete these tasks they award Rox (and experience points).  

Selling unwanted items to Dodgy Deals on Sludge Street and even winning Random Rox prize competitions in the Daily Growl are other ways of making Rox. "Random Rox" prizes are given out in the Daily Growl if you win a competition or your comment is chosen. Random Rox prizes are normally 250 Rox and other contests are 5,000. Also in the Daily Growl if a playet is MonSTAR of the Week or Room of the Week, they get 2000 Rox.

If players are a Member, they get exclusive access to the Port, where shaking Rox Trees, gets you around 200-300 Rox each week. Super Moshis can also earn Rox by going to the secret area in the Volcano that grants access to the Rox Stone or by finding all the EPICS in missions to get 500 Rox.

In Series 4, 5, 6 and possibly 7 figures, on the collector cards, on the back there is a secret code for free Rox. Rox codes also come with the five packets and with the Code Breakers Mash Up cards.

Players can also get Rox by entering special codes into I.G.G.Y. All good Moshi Monsters websites update regularly iwith new codes.
