While Dig a Garden currently has no active promo codes, there are still ways to get free rewards. This guide covers every method for obtaining free items and Diglets without spending Robux.
Free Rewards Available Now
| Reward | How to Get | Value |
|---|---|---|
| Group Drill (A-tier) | Join The Heap group | Excellent — free A-tier drill |
| Starter Drill | Free at start | Starting drill |
| All items from drilling | Automatic discovery | Main income source |
| Offline Diglets | Leave drills running | Passive 24/7 income |
The Group Drill is by far the most valuable free reward currently available. It is an A-tier drill that costs nothing and significantly accelerates early-game progression.
How to Claim the Group Drill
The Group Drill is the single most important free reward in Dig a Garden, and claiming it takes less than two minutes. Here is a step-by-step walkthrough:
- Open the Roblox website or app and navigate to The Heap group page. The group is official and managed by the game's developers.
- Click the "Join Group" button on the group page. You must be logged into your Roblox account. There is no approval wait — joining is instant.
- Launch Dig a Garden on Roblox. The game automatically detects your group membership when you load in.
- Check your drill inventory. The Group Drill will appear alongside your other available drills. If it does not appear immediately, try rejoining the game.
- Place the Group Drill on your plot. It operates the same way as any other drill — position it and it begins digging automatically.
Important Notes on the Group Drill
- You only need to join the group once. Your membership persists across sessions.
- If you leave The Heap group, you will lose access to the Group Drill. Any placed Group Drills will stop functioning until you rejoin.
- The Group Drill can be placed alongside other drills, so you can run it simultaneously with your Starter Drill or any purchased drill.
- There is no limit to how many Group Drills you can place — each one you earn through group membership is yours to keep as long as you remain in the group.
Free Drill Comparison and Progression Path
Understanding how free drills compare to each other and to paid options helps you plan your progression without spending Robux. The table below compares every drill in the game, highlighting which are free and which require Diglets or Robux.
| Drill | Tier | Cost | Free? | Dig Speed | Best Use |
|---|---|---|---|---|---|
| Starter Drill | C | Free (default) | Yes | Slow | First few minutes only |
| Standard Borer | B | 500 Diglets | No | Moderate | Early upgrade from Starter |
| Group Drill | A | Join The Heap | Yes | Fast | Primary drill for most F2P players |
| Turbo Digger | A | 5,000 Diglets | No | Fast | Sidegrade to Group Drill |
| Deep Piercer | A | 25,000 Diglets | No | Fast | Better rare item odds |
| Mega Borer | S | 100,000 Diglets | No | Very Fast | End-game F2P goal |
| Galaxy Drill | S | Gamepass (off-sale) | No | Very Fast | Currently unobtainable |
Free-to-Play Progression Roadmap
For players committed to never spending Robux, here is the optimal progression path using only free rewards and Diglets earned through gameplay:
- Start with the Starter Drill — Place it immediately and let it dig while you learn the basics.
- Join The Heap and claim the Group Drill — Do this within your first session. The Group Drill outclasses the Starter Drill dramatically and will be your workhorse for a long time.
- Run both drills simultaneously — Place the Starter Drill and Group Drill on your plot together. Two drills mean double the item discovery rate.
- Save for the Standard Borer (500 Diglets) — Your third drill slot increases overall income. Sell items regularly to avoid inventory caps.
- Upgrade to the Turbo Digger (5,000 Diglets) — Replace the Starter Drill once you can afford this. You now have three strong drills running.
- Aim for the Mega Borer (100,000 Diglets) — This is the ultimate F2P drill. It matches the premium Galaxy Drill in tier and makes end-game content fully accessible.
The key insight is that the Group Drill eliminates the need to grind through the early B-tier drill phase. By joining The Heap group immediately, you skip straight to A-tier performance at zero cost.
Maximizing Passive Income from Free Drills
Dig a Garden's offline progression system is the most powerful free reward in the game — even more impactful than the Group Drill over time. Understanding how to optimize this mechanic determines how quickly you progress without spending real money.
How Offline Progression Works
When you leave the game, your placed drills continue digging items automatically. The next time you log in, all discovered items appear in your inventory ready to sell. This means your drills generate Diglets 24 hours a day, 7 days a week — even when you are sleeping or at school.
However, there is a critical limitation: inventory caps. When your inventory fills up, your drills stop generating new items until you log back in and sell. This means longer offline sessions do not always equal more Diglets.
Offline Earnings Optimization Table
| Strategy | Offline Time Before Cap | Estimated Diglets Earned | Action Required |
|---|---|---|---|
| 1 Starter Drill | ~2-4 hours | 50-150 | Log in 4-6 times daily |
| 1 Group Drill | ~1-3 hours | 100-400 | Log in 3-5 times daily |
| Starter + Group Drill | ~1-2 hours | 150-550 | Log in 5-8 times daily |
| 3 A-tier drills | ~30-90 minutes | 300-1,200 | Log in every hour ideally |
| Full high-tier setup | ~20-45 minutes | 500-2,000 | Frequent check-ins needed |
Tips to Maximize Offline Diglets
- Always sell before logging off — Start every offline session with an empty inventory to maximize the time before your drills stop.
- Place your strongest drills — Higher-tier drills dig faster and find rarer items. Prioritize placing A-tier and S-tier drills over C-tier ones.
- Check in during the day — Even a 30-second login to sell items can double your daily Diglet earnings compared to checking once in the morning and once at night.
- Upgrade inventory capacity — If the game offers inventory expansions, invest in them early. More inventory space means longer profitable offline sessions.
- Weekend strategy — On days when you can check in more frequently, run all your best drills. On busy days, accept that your inventory will cap and you will earn less — but you will still earn something.

Free Items and Rarity Breakdown
Every item your drills discover is technically a free reward — you never pay Robux for individual items. Understanding the item rarity system helps you estimate your Diglet income and know which finds are most valuable.
| Rarity | Approximate Find Rate | Sell Value Range | Notes |
|---|---|---|---|
| Common | ~60-70% of finds | 1-10 Diglets | Fills inventory quickly; sell immediately |
| Unusual | ~20-25% of finds | 15-50 Diglets | Decent income; keep an eye out |
| Scarce | ~8-12% of finds | 80-250 Diglets | Significant earnings when found |
| Legendary | ~1-3% of finds | 500-2,000+ Diglets | Game-changing; always sell promptly |
How Drill Tier Affects Item Rarity
Higher-tier drills do not just dig faster — they also have better odds of finding rarer items. This is why the free Group Drill is so valuable compared to the Starter Drill:
- C-tier (Starter Drill): Finds mostly Common items with rare Unusual drops. Scarce and Legendary finds are extremely uncommon.
- B-tier (Standard Borer): Noticeably more Unusual items. Scarce items appear occasionally.
- A-tier (Group Drill, Turbo Digger, Deep Piercer): Strong Unusual drop rates, regular Scarce finds, and occasional Legendary items.
- S-tier (Mega Borer, Galaxy Drill): Frequent Scarce drops, Legendaries appear with reasonable regularity.
This means the Group Drill does not just save you time — it fundamentally improves the quality of items you find, which accelerates your Diglet earnings even beyond what the raw dig speed would suggest. Learn more about drill performance in our Best Drills Tier List.

Common Mistakes That Cost Free Rewards
Even though Dig a Garden is generous with free content, players frequently make mistakes that reduce their free earnings. Avoid these pitfalls:
1. Not Joining The Heap Group Immediately
The biggest mistake is waiting to join the group. Every minute you spend drilling with the Starter Drill instead of the Group Drill is wasted earning potential. Join the group before your first gameplay session.
2. Letting Inventory Cap Out Overnight
If you log off with a nearly full inventory, your drills will stop producing within minutes. Always sell everything before closing the game. A full inventory means zero passive income until you return.
3. Leaving the Group After Claiming the Drill
Some players join the group, claim the Group Drill, then leave. This causes the Group Drill to stop working. You must remain in The Heap group for the drill to function.
4. Ignoring the Starter Drill After Getting the Group Drill
The Starter Drill may be weak, but it still produces items for free. Running both drills simultaneously is always better than running just one. Place every drill you own — there is no downside.
5. Saving Diglets Too Long Before Upgrading
Hoarding Diglets beyond your next upgrade slows your progression. Every Diglet sitting unspent is a Drill upgrade you do not have yet. Buy the next drill in your progression path as soon as you can afford it — the increased earning rate pays for itself quickly.

FAQ
Q: What is the best free reward in Dig a Garden? A: The Group Drill (free, A-tier) from The Heap group. It is the most valuable free item in the game.
Q: Will there be promo codes in the future? A: Many Roblox games eventually add promo codes. It is reasonable to expect Dig a Garden to add a code system in the future.
Q: Can I get free Diglets without drilling? A: Not currently. Drilling (and selling discovered items) is the only way to earn Diglets. However, the offline mechanic means you earn Diglets without actively playing.
Q: Is Dig a Garden completely free to play? A: Yes! All drills can be earned through gameplay. The only paid option (Galaxy Gamepass) is currently off-sale and not necessary for end-game content.
Q: What happens if I leave The Heap group? A: Your Group Drill will stop functioning. Any Group Drills placed on your plot will cease digging until you rejoin the group. Your other drills are unaffected.
Q: How often should I log in to sell items for maximum free Diglets? A: With two A-tier drills running, logging in every 1-2 hours to sell is ideal. If you can only check in 2-3 times per day, you will still earn significant passive Diglets — just not at maximum efficiency. Always sell everything before logging off.
Q: Can I get the Galaxy Drill for free? A: No. The Galaxy Drill was only available through a Gamepass purchase with Robux, and it is currently off-sale. The Mega Borer (S-tier, 100,000 Diglets) is the best free alternative and matches it in tier ranking.
