As you try your hand at survival in Roblox Ink Game, you can get your hands on powers to give you a boost in each challenge.

To really do well, you have to spend a lot of time playing, but you can also spend some real money on Robux or gems, two distinct types of in-game currency that can earn you stronger fighters.

Roblox's "Grow A Garden" game is breaking popularity records. A 16-year-old created it. How did it blow up? I tried it myself.

Some popular Roblox games then have their own virtual currency. Players must first convert real-world money into Robux, then convert the Robux into a game’s currency of “diamonds” or “gems”.
