Explanation for the Hamster Kombat game
It all starts with the hamsters you can obtain by tapping the female in the base. You'll see a number increasing in the top left corner. These hamsters are the foundation for pretty much everything.

Additionally, you can buy different colored houses on the map. What I find cool about this is that they are actual existing houses from OpenStreetMap. These houses come in 4 colors (your first house is yellow, but it's essentially just one of the other 4 colors). In these houses, you can obtain items. You'll need these items for other tasks in the houses and for base upgrades. More on that later.

You'll also encounter the 4 house colors in the hamsters tab. When you tap the lady at the base, large objects sometimes roll down. These are like chests for fighting hamsters. You can open these hamster chests at the top of the hamsters tab. This makes your 4 mafia groups larger and stronger.
In your houses, you can use a stronger mafia group to fight against other groups. Once you reach level 10, you can upgrade your house to the next phase, where you can find other items.
You might need these items to upgrade your base (base tab, construction button). At first, an important upgrade for your base is the recreation room. This allows you to recruit more hamsters in the base to deploy. But you will also need upgrades for other stuff.
Extra tips
- Houses with an edge on the roof are special houses. In these, you can obtain things you can't get in regular ones.
- Sometimes you get stuck because you need an item that you can't make in your houses yet. You can also buy things with those red caps in the shop. These chests sometimes contain exactly what you need.
- A lot of features are still coming. Such as clans and the ability to claim more areas or something. Maybe also that more areas of the real map will become available. So the further you are, the more interesting that becomes.
