Power-ups, chests and coins
Power-ups give your crowd a short boost, chests give you free units, and coins buy upgrades in the shop. Here is what each one does, with the real numbers from the game.
Power-ups on the map
There are 22 power-ups on the map. Walk into one to use it. When a power-up is used, it comes back 12 seconds later at a new spot, as a random type:
| Power-up | What it does | Chance |
|---|---|---|
| Speed | 45% faster for 8 s | 35% |
| Shield | no losses for 6 s | 25% |
| Magnet | pulls grey people for 10 s | 22% |
| Chest | 11 units + 10 coins | 18% |

Speed
- 8 seconds
- 45% faster
Your crowd moves 45% faster for 8 seconds. Use it to catch a green-ring crowd, to escape from a red one, or to reach a far chest quickly.
Speed matters because crowds slow down as they grow: a full crowd is about 19% slower, and fighting slows you to 70% speed. A speed boost more than makes up for either one.

Shield
- 6 seconds
- No losses
For 6 seconds your crowd loses no units, enemy crowds won't attack you, and arrows can't hurt you. Every round also starts with an 8-second shield.
Pro tip: crowds that touch still fight, but only you are safe. Walk into a yellow-ring crowd while your shield is on: it loses power every second and you lose nothing. Just finish the fight or leave before the 6 seconds end.

Magnet
- 10 seconds
- 240 px
For 10 seconds, the magnet pulls grey people to you from up to 240 pixels away. It is best in a busy spot with lots of grey people around, especially ones with a gold ring (archers, barbarians and giants).

Chests
- 11 units
- +10 coins
A chest gives you 8 soldiers, 2 archers and 1 barbarian at once. That is 15 power, plus 10 coins.
Look for chests inside forts: squares of stone walls with 4 doors. A map has up to 6 forts. Sometimes a chest is also out on the open map: 18% of the power-ups that come back are chests. On the minimap in the bottom-left corner, chests are yellow dots.
Only you can open chests. Enemy crowds can't, so nobody will steal yours: go for it when the way is safe.

How to earn coins
- Coin piles: 45 on the map, 5 coins each. A pile comes back 8 seconds after you take it. Only you can pick them up.
- Chests: 10 coins each.
- End of the round: 10 coins for each crowd you beat, half your biggest crowd size, all the coins you picked up, and a rank bonus: 150 for 1st, 90 for 2nd, 60 for 3rd and 20 for everyone else.
- New level: 50 coins every time you level up.
- Daily reward: 20, 30, 40, 50, 60, 80 and 150 coins for days 1 to 7 in a row. Miss a day and you start again at day 1.
- Daily missions: 3 a day, worth 30 to 120 coins each. Collect them in the Missions screen.
There is no rank bonus if your crowd was beaten or you pressed END ROUND. And on Treasure day in the Daily Challenge, the map has twice as many coins.
| Beat 5 crowds (5 × 10) | 50 |
| Biggest crowd: 120 units (120 ÷ 2) | 60 |
| Picked up 12 coin piles and 2 chests | 80 |
| Finished 1st | 150 |
| Total | 340 coins |
Spending coins in the shop
Each upgrade costs more at every level: the price is the base price × the next level. So level 3 of Bigger Start costs 40 × 3 = 120 coins.
| Upgrade | Base price | All levels |
|---|---|---|
| Bigger Start +2 soldiers, 10 levels | 40 | 2,200 |
| Archer Squad +1 archer, 5 levels | 60 | 900 |
| Barbarian Squad +1 barbarian, 5 levels | 80 | 1,200 |
| Giant Friend +1 giant, 3 levels | 200 | 1,200 |
| Fast Feet +4% speed, 5 levels | 70 | 1,050 |
| Recruiter +5% of beaten enemies join, 5 levels | 90 | 1,350 |
The first levels give the most for your coins: Bigger Start level 1 adds 2 power for 40 coins, and Giant Friend level 1 adds 9 power for 200 coins.
You can also buy crowd colours: Blue is free, Gold and Purple cost 150, Pink and Black 250, and White 400.
