Free Steam Market items drop every hour (without any limits)

Play Soccer Online: Ball 3D in any mode you want and after every 1 hour of playing you will get 1 key and 1 box (there are no limits, you can get as many keys as you can every day).

Then you can use these keys to open boxes and get free Steam Market items. You can sell these items on the Steam Market, trade with others or keep them for yourself and use in the game.

There are 5 types of items: common, uncommon, rare, very rare, legendary.

What you will get from the box is visible (marked with a star icon) before you open it, so you know what you get before using the key. You can use every key to open any box you want. It is best to just preview all boxes and get the item that you want the most (from those currently marked with the star symbol).

Every new players will also get 5 free keys + 20 boxes (the items will drop a few minutes after you start the game for the first time).

New crafting system will be added to the game in the future that will let you craft even more rare items using your existing items, so it is worth collecting them.
