Where to spend

You never have enough of everything. Here is the order that keeps you moving.

Coins go to units first

Coins buy almost everything, which makes them the easiest to waste. Priority:

• The units you actually play. Leveling your core is what wins battles and climbs arenas. Everything else is secondary.
• Castle width, then hardness. More blocks help sooner than a higher material tier. See Castle.
• A helper or wheel you use. Only level the ones you bring to battle.

Wood is castle-only

Wood is spent alongside Coins on castle blocks and foundations, and nothing else. If Wood is piling up, your castle is behind; put it to work.

Gems buy time, not power

Gems skip build and upgrade timers. They do not make a unit stronger, so there is no rush to spend them on gameplay. Save them for a wait that is genuinely in your way.

Cards are the real bottleneck

Cards are tied to one unit each, so they are the scarcest currency by far. Do not scatter them. Wild Cards of a rarity fill in for any unit of that rarity, so hold them for whichever core unit you are pushing. The cost curves show how many you will need.

Raise the forge to unlock the rest

Your forge level gates higher castle levels, more helpers, and more wheels. When your building side stalls, a stuck forge is usually the reason, so keep it climbing alongside your roster.
