Best Method to Get Gems in ASTD X

The best method to get gems in ASTD X is to claim every available reward first, then spend your active playtime on the repeatable mode with the highest verified gems per minute on your account—usually a fast, reliable stage or challenge you can clear without pausing to upgrade or retry.

Use this route in order

  1. Collect rewards that do not require a grind

    Check the daily reward, quests or missions, achievements, and any event or update reward the game currently offers. Claim completed rewards before starting a long run so you do not leave gems uncollected. If the game has a working redemption-code feature, use only codes posted through the game’s official channels; codes expire, and old code lists can waste time.

    These rewards may not be repeatable, but they often have the best return on your time because they take only a few minutes to check. Read each mission’s wording: a reward might require a particular mode, unit, or number of clears rather than simply logging in.

  2. Finish quick, overlapping missions

    Choose tasks that can be completed during the same run. For example, if a mission asks for a stage clear and another tracks enemies defeated, play a stage that advances both. Avoid spending extra time on a difficult task for a small gem payout unless it also progresses a larger reward track.

    Prioritize guaranteed rewards over uncertain drops. A repeatable clear with a known payout is easier to plan around than a mode where gems are only a chance reward.

  3. Test repeatable activities by gems per minute

    Do not assume the hardest stage is the best farm. Time one complete run, including loading, setup, and claiming the reward. Divide the gems earned by the total minutes. Repeat once if the run had an unusual delay, then compare the result with another activity you can clear consistently.

    Use the exact mode names and rewards shown in your current game version. ASTD X can change through updates, and rewards, event schedules, or available modes may differ. If a mode does not display a gem reward and you cannot confirm one from a recent clear, do not count it as a gem farm.

  4. Repeat the best reliable run, not the theoretical best run

    Pick the activity that gives the strongest combination of gems per minute and dependable clears. A slightly slower run that succeeds every time can beat a faster run that frequently fails or needs a full replay. If the game offers an auto or repeat option, use it only after confirming that it completes the activity and claims rewards correctly.

Compare your options with a simple calculation

The table below shows how to compare activities; its figures are examples for the calculation, not guaranteed ASTD X payouts. Replace them with the rewards and timings you see in your own game. Include loading and claim time so the comparison reflects your actual session.

Activity (example) Gems per clear Total time per clear Calculated rate Best use
Short repeatable stage 12 4 minutes 3 gems/minute Focused farming if clears are consistent
Longer challenge 30 12 minutes 2.5 gems/minute Choose if it also advances a valuable mission
Daily task bundle 60 8 minutes of active work 7.5 gems/minute Complete early, while tasks are convenient
Unverified drop activity Unknown 10 minutes Cannot calculate Test once; do not build a routine around it yet

For example, if a stage pays 12 gems and takes four minutes from start to reward claim, its rate is 12 ÷ 4 = 3 gems per minute. If a retry adds two minutes and is needed once every four attempts, include that failure time in your average. This prevents a fragile strategy from looking better than it performs in practice.

Choose the route that fits your session

Your situation Recommended priority Why
You have 5–10 minutes Claim login and completed rewards; finish the shortest mission you can complete Setup and loading can erase the value of a long run
You have 20–30 minutes Clear overlapping missions, then repeat your measured best stage Combines one-time progress with predictable farming
You have a long session Complete limited-time rewards first, then farm the best reliable repeatable activity Event or daily rewards may expire; repeatable farming can wait
Your clears are inconsistent Use a lower, dependable difficulty or stage Failed runs reduce the real gems-per-minute rate
You are saving for a specific banner or unit Set a gem target and stop spending on optional pulls Unplanned spending delays the goal without improving farming speed

Spend resources to protect your farming rate

Keep gems for the banner, unit, or upgrade you are intentionally saving toward. Before spending, check whether the game publishes the banner’s end date and whether your balance is enough for the number of pulls or purchases you want. Do not spend gems to speed up a farm unless the saved time is worth more than the gems spent.

Use coins, materials, and upgrade resources to make your clears more consistent when they are available for that purpose. A modest upgrade that removes a common failure point can improve your long-term gem income more than attempting a higher stage immediately. Avoid upgrading every unit indiscriminately: prioritize the units or team changes that shorten your chosen run or prevent losses.

Common farming mistakes

  • Chasing the largest payout: A bigger reward can still be worse if the run takes much longer. Compare the rate, not the payout alone.
  • Ignoring reward-claim steps: Confirm the gems were added after a clear. If they were not, check whether the mode has a separate results or claim screen.
  • Repeating a mode based on an old guide: Updates can change rewards and event availability. Verify the current payout in-game.
  • Taking avoidable risks: A failed run costs time and may provide no gems. Farm at a difficulty you can finish consistently.
  • Using unofficial generators or account-sharing offers: These can put your account or login details at risk. Legitimate gems come through the game’s own rewards and purchase systems, not external tools promising unlimited currency.

A practical daily routine

Start by collecting available login, quest, and event rewards. Next, complete the quickest missions that overlap with your normal play. Then spend the remaining session repeating the activity you have timed and confirmed pays gems. Recheck the routine after a major update or when an event begins, since a temporary reward can make a different activity the better choice.

In short, the best method to get gems in ASTD X is not a single universally fastest stage: it is a measured routine of free claims, efficient mission completion, and repeatable clears with a proven gems-per-minute rate. Verify payouts in your current version, account for failed runs and loading time, and protect the gems you are saving for.

Frequently asked questions

How can I tell whether a mode is actually worth farming?

Time one complete run from the start through loading, setup, and claiming the reward, then divide the gems earned by the total minutes. Repeat the measurement if the run had an unusual delay. Compare that rate with another activity you can clear consistently, and include retry time or failed runs in the average rather than judging the payout alone.

What should I do if a mission does not clearly say how to earn its reward?

Read the mission wording carefully and check whether it requires a particular mode, unit, or number of clears instead of simply logging in. Choose missions that overlap during the same run whenever possible. If a task requires extra time for only a small gem payout and does not advance a larger reward track, prioritize a more useful guaranteed reward instead.

Can I use auto or repeat farming immediately?

Use an auto or repeat option only after confirming that it completes the activity and claims the rewards correctly. A convenient option is not automatically profitable if it stops before the reward screen or fails a clear. First verify the payout in your current game version, then use the option only for an activity with a dependable gems-per-minute rate.

What should I do when an activity has an unknown gem reward?

Test the activity once if you want to investigate it, but do not build your farming routine around it while the reward remains unverified. If the mode does not display a gem reward and you cannot confirm one from a recent clear, leave it out of your gems-per-minute comparison. Use a repeatable activity with a known payout instead.

How should I handle gem farming when I am saving for a banner or unit?

Set a gem target and avoid optional pulls or other unplanned spending that delays it without improving farming speed. Check whether the game publishes the banner’s end date and whether your balance is enough for the purchases or pulls you want. Keep farming with the reliable route, and spend upgrade resources only when they help shorten runs or prevent losses.
