Understanding how Dig a Garden works is essential for maximizing your progress. This guide breaks down every core mechanic in the game, from drill placement to the offline earnings system.
The Core Gameplay Loop
At its heart, Dig a Garden follows a simple but satisfying loop:
Buy Drills → Place on Plot → Wait for Items → Sell for Diglets → Buy Better Drills
This loop repeats infinitely, with each cycle making you more efficient. The beauty of the game is that the "Wait for Items" step happens automatically — even while you are offline.
| Step | Action | Time Required |
|---|---|---|
| 1 | Buy/upgrade drill | 1-2 minutes |
| 2 | Place drill on plot | Instant |
| 3 | Wait for items to dig up | Automatic (minutes to hours) |
| 4 | Collect and sell items | 1-5 minutes |
| 5 | Buy next drill upgrade | 1-2 minutes |
How Drills Work
Drills are the primary tools in Dig a Garden. Each drill has three key attributes:
- Dig Speed: How quickly the drill discovers items. Faster drills find more items per hour.
- Item Quality: The rarity distribution of items the drill finds. Higher-tier drills have better chances of finding Scarce and Legendary items.
- Diglets Per Hour: The overall Diglets earning rate, combining speed and item value.
Drills operate automatically once placed. You do not need to manually activate them — they dig continuously until your inventory fills up. The critical thing to remember is that drills never stop working as long as there is inventory space.
Drill Placement Strategy
Your plot has a limited number of slots for drills. The optimal strategy is simple: fill every slot with the best drill you can afford. Empty slots are wasted potential earnings.
You can remove drills from your plot, but you do not get a full refund. Always upgrade rather than remove when possible — selling a drill to buy a slightly better one usually results in a net loss.
Complete Drill Comparison & Stats
Knowing which drill to aim for is half the battle. Below is a comprehensive comparison of every drill available in Dig a Garden, ranked from basic starter equipment to the pinnacle of F2P and premium mining.
| Drill Name | Tier | Cost (Diglets) | Dig Speed | Rarity Bias | Notes |
|---|---|---|---|---|---|
| Starter Drill | C | 0 (Free) | Very Slow | Common | Your first drill; replace ASAP |
| Standard Borer | B | 500 | Slow | Unusual | First meaningful upgrade |
| Group Drill | A | 0 (Free) | Moderate | Scarce | Requires joining The Heap |
| Turbo Digger | A | 5,000 | Fast | Scarce | Solid mid-game workhorse |
| Deep Piercer | A | 25,000 | Very Fast | Scarce/Legendary | High Legendary chance for A-tier |
| Mega Borer | S | 150,000 | Extreme | Scarce/Legendary | Best Free-to-Play drill |
| Galaxy Drill | S | N/A (Premium) | Maximum | Legendary | Off-sale gamepass exclusive |
The jump from A-tier to S-tier is massive. If you are aiming for the absolute best F2P setup, your ultimate goal is to fill every plot slot with Mega Borers. Check out our best drills guide for a deeper dive into maximizing your specific loadout.
The Item Rarity System
Items in Dig a Garden come in four rarity tiers, each with different sell values and drop rates:
| Rarity | Tier | Value | Drop Rate | Best Drill |
|---|---|---|---|---|
| Common | C | Low | Very Frequent | Any drill |
| Unusual | B | Moderate | Uncommon | Standard Borer+ |
| Scarce | A | High | Rare | Turbo Digger+ |
| Legendary | S | Massive | Ultra Rare | Deep Piercer / Galaxy |
The rarity system means that higher-tier drills are not just faster — they also find better items. A Mega Borer (S-tier) finds significantly more Scarce and Legendary items than a Starter Drill (C-tier), making the upgrade path worthwhile even beyond just speed.
Because Legendary items sell for a massive premium, an S-tier drill with a slower dig speed can actually out-earn an A-tier drill with a faster dig speed. Always factor in the rarity bias when choosing your next upgrade.
The Diglets Economy
Diglets are the in-game currency used to buy new drills and upgrades. The key principles of the Diglets economy are:
- Diglets have no known cap — you can accumulate as many as you want
- Selling items is the only way to earn Diglets — there is no other income source
- Drills are the best investment — better drills earn more Diglets, creating a positive feedback loop
- Inventory limits are the real cap — a full inventory stops all earnings
Diglets Spending Priority
When deciding how to spend your Diglets, follow this priority order:
- Next drill upgrade — Always the highest priority
- Fill empty plot slots — More drills = more items = more Diglets
- Plot size upgrades (if available) — More slots for more drills
- Save for premium options (only if F2P options are exhausted)
Never hoard Diglets if you can spend them on a drill upgrade. An unused Diglet is a Diglet that isn't working for you. For specific ways to boost your income, see our Dig a Garden codes list for free rewards.
Early Game Progression Walkthrough
Starting out in Dig a Garden can feel slow, but a structured approach will accelerate your earnings dramatically. Follow this step-by-step walkthrough to establish a strong foundation:
Step 1: Claim Your Plot and Starter Drill When you first spawn, claim an empty garden plot. You will automatically receive a Starter Drill. Place it immediately—every second counts.
Step 2: Join The Heap for the Group Drill Open the Roblox group page for The Heap and join. You can then claim the Group Drill for free in-game. This A-tier drill drastically outperforms the Starter Drill and costs nothing.
Step 3: The Standard Borer Milestone Let your Starter and Group drills run. Check back every 15-30 minutes to sell items. Your first purchase goal is the Standard Borer (500 Diglets). Place it and remove the Starter Drill.
Step 4: Scaling Up to Turbo Digger With two solid drills running, save up 5,000 Diglets for the Turbo Digger. Replace the Standard Borer once you can afford it.
Step 5: The Long Grind to Mega Borer Your final F2P milestone is the 150,000 Diglet Mega Borer. This takes time, but logging in frequently to empty your inventory prevents downtime.
| Milestone | Target | Estimated Time (Active Play) |
|---|---|---|
| First Upgrade | Standard Borer (500 Diglets) | 30-45 minutes |
| Group Integration | Group Drill (Free) | 5 minutes |
| Mid-Game Drill | Turbo Digger (5,000 Diglets) | 2-3 hours |
| Late-Game Drill | Deep Piercer (25,000 Diglets) | 6-8 hours |
| F2P Endgame | Mega Borer (150,000 Diglets) | 1-2 days |
Offline Progression Mechanics
The offline progression system is Dig a Garden's defining feature. Here is exactly how it works:
- When you leave the game, your drills continue digging automatically
- Discovered items accumulate in your inventory
- If your inventory fills up, drilling stops — no new items are discovered
- When you rejoin the game, all accumulated items are waiting for you
- Sell items to free up inventory space, and drilling resumes
The maximum offline earnings depend on:
- Your drill setup (tier and number of drills)
- Your inventory capacity
- How long you are offline
With S-tier drills, you can earn significant Diglets overnight — potentially millions if you check in regularly to sell items.
Calculating Your Offline Cap
To figure out how long you can safely stay offline, divide your total inventory capacity by your combined items-per-hour rate. For example, if your inventory holds 200 items and your drills produce 50 items per hour, your offline cap is 4 hours. Leaving the game for longer than 4 hours means your drills sit idle for the remaining time. Use this calculation to set alarms or reminders to log in and sell.
Inventory Management
Inventory management is the most important skill in Dig a Garden. A full inventory completely stops your earnings, which is the number one reason players fall behind.
Best practices:
- Log in every 2-4 hours to sell items and free inventory space
- Use the bulk sell button to sell everything at once
- Never leave your inventory full overnight — set a reminder to check before bed
- Higher inventory capacity = longer offline sessions before capping

Joining The Heap Community
Dig a Garden is developed by The Heap, and being an active member of their Roblox community provides tangible in-game benefits. By joining the group at https://www.roblox.com/communities/35892097/The-Heap, you gain access to the free Group Drill, which is an A-tier item that completely skips the early-game grind.
Beyond the free drill, The Heap group occasionally posts announcements for updates, events, and potential future codes. Being in the group ensures you are among the first to know when new content drops or if the Galaxy Gamepass goes back on sale.
Understanding Gamepasses
Dig a Garden currently has one gamepass:
| Gamepass | Drill | Status | Value |
|---|---|---|---|
| Galaxy Gamepass | Galaxy Drill (S-tier) | Off-Sale | Premium |
The Galaxy Gamepass was previously available for Robux and unlocked the Galaxy Drill — the best drill for legendary item hunting. It is currently off-sale, meaning it cannot be purchased. If it returns, it provides a significant advantage for players willing to spend Robux.
