Make your Coins go further

Where the Coins come from

The official description gives two parts of the destruction income: Coins for broken blocks and bonuses at listed destruction percentages. It also announces SMASH for 5,000 Coins.

For planning, use the Coin total displayed in your game. Record it before a timed run and again at the end. If you spend Coins or claim a code during the measurement, that balance change is not a clean measure of your destruction income.

The 25 / 50 / 75 / 95 checkpoints

For example, a meter at 62% is 13 percentage points away from 75%. A meter at 82% is 13 points away from 95%. These differences describe progress, not how many attacks or minutes the remaining buildings require.

Our suggestion is to use the next checkpoint as a session goal. Measure the time and Coin gain needed to reach it, then compare the result with another run under similar conditions.

Is the next checkpoint worth the time?

A short percentage gap can still take time when the remaining targets are scattered. Record your balance and progress before working toward a checkpoint, then record them again when you reach it. Include aiming, travel or target-search time in the elapsed minutes you measure.

Compare the net Coins earned during that interval with its duration. This includes any checkpoint reward that actually reached your balance, without assigning an invented payout to the threshold.

Worked example with hypothetical inputs: moving from 82% to 95% takes 3 minutes and adds 1,200 Coins, giving 400 Coins per minute. A comparable interval in another session adds 1,000 Coins over 2 minutes, giving 500 Coins per minute. The second interval earns faster in this example; reaching the higher percentage alone does not establish the better rate.

Compare several intervals with similar starting progress, equipment and player activity. If your goal is completing a city rather than saving quickly, reaching the checkpoint can still be the goal even when its measured earning rate is lower. Use the run comparison tool to calculate your own rates.

Unlock budget calculator

Enter the price you see in the game, your current balance and your own earning rate. The calculator estimates how much more you need and how long that gap would take at a steady rate.

Formula: Coin gap = maximum of zero and (target price − current balance − any reward not yet included). Estimated minutes = Coin gap ÷ measured Coins per minute.

Example inputs: a 10,000-Coin target, 7,200 Coins in the balance and a measured rate of 400 Coins per minute leave a gap of 2,800 Coins. At that rate, the saving estimate is 7 minutes. The example is arithmetic, not a quoted weapon price or promised game income.

Do not add the code reward twice. If you use the balance displayed after claiming it, leave the extra-reward option unchecked. An estimate can change when you switch maps, equipment, settings or session conditions.

Compare two Coin farming runs

Use net Coins earned and actual elapsed minutes. Include aiming, waiting and time spent finding remaining targets. Keep code claims and purchases outside the measurement window.

Formula: Coins per minute = net Coins earned ÷ elapsed minutes. Compare rates rather than just the biggest final total.

Example inputs: 1,200 Coins over 3 minutes is 400 Coins per minute. A different run earning 1,500 over 5 minutes is 300 Coins per minute. The shorter run has the higher measured rate even though it earned fewer total Coins.

Repeat close results over several sessions. Keep the same map when evaluating weapons and the same weapon when evaluating maps. Record starting destruction progress and other players’ activity; these conditions can influence what a comparison means.

Turn the result into a spending decision

Choose one target at a time. If your balance already covers the price, consider whether buying now serves your next goal or delays another unlock you want more. If a gap remains, use the estimate to plan a session rather than assuming every minute will have identical income.

A larger visual effect is a reason to try a weapon, not enough by itself to prove a better farming rate. Use the weapon comparison method and keep your own run notes. For a new environment, read the map practice guide.
