How to Get Free Gems in Diggy's Adventure

Leveling up (steady, predictable gem income)

Every level-up grants instant energy, and gems turn up as level rewards as you climb. There is no published table of exactly which levels pay how many gems, so treat it as a steady drip rather than a schedule you can plan around.

• Rush mines to level faster: Dig only quest-required tiles to save energy and complete more quests per session.
• Save achievement rewards until you need XP: Achievements grant XP, and a level-up is what turns that XP into energy and gems.
• Place pillars at level 100+: Buy pillars with surplus materials for XP, then cash in the level-up when you actually want it.

Levelling is the most reliable free gem source over time, particularly in the early and mid game where levels come quickly.

Achievements (one-time gem bursts)

Achievements reward gems, green rings, XP and coins on completion, and are tied to mine completion, treasure collection, event participation and camp upgrades. They are the highest-value gem source per unit of effort in the game.

• Track progress in the tasklist: Prioritise the achievements that actually grant gems rather than clearing them in order.
• Watch the ad to double: After completing one you can watch an ad to double the gems, green rings, XP and coins. Equipment items do not double.
• Batch your claims: Save several completed achievements and claim them in one session to stack XP and trigger a level-up alongside the gems.

Achievement gems are one-time, but they add up quickly if you systematically complete quests, collect treasures and take part in events.

Scattered gems in mines (exploration rewards)

Gems are placed throughout mines as collectible items, often behind puzzles or on hard-to-reach tiles. They are not guaranteed in every mine, and story mines carry them more densely than repeatable farms.

• Use the Last Tile Finder: This extra, bought with copper, locates what you have missed before you leave a mine.
• Focus on story mines: Main quest mines tend to have more gem placements than repeatable resource farms.
• Revisit old mines: Some repeatable mines refresh, so a high-yield one is worth checking again rather than assuming it is spent.

Mine gems are irregular but consistent over a long enough run. Treat them as a bonus on top of your other methods rather than something to farm deliberately.

Event pass free row (recurring gem source)

Every event includes an Event Pass with a free reward row, and gems appear on it at certain point thresholds. You earn Event Points by playing event locations, completing event quests and farming event repeatables. The premium row costs money; the free row does not, and it is where a no-spend player should focus entirely.

• Start events on day one: Event Points accumulate over the whole run, so a late start costs you the higher free-row milestones.
• Find the high-yield locations: Some event mines pay more Event Points per energy spent than others. Work out which early.
• Stack with special weeks: Double Production Week and the Candyland or Builder weeks accelerate the material and caravan income that feeds Event Points.

Free row gems vary by event, but regular participation across a month adds up to a meaningful total without spending anything.

Reward codes (instant drops, but time-limited)

Pixel Federation runs an official reward code system, and codes sometimes contain gems. They are announced on Instagram, Facebook and Reddit rather than published as a permanent list, and most are live for days rather than weeks.

Lucky Cards Tent (random draws, gems are rare)

The Lucky Cards Tent offers three draws per 8-hour cycle, so nine rewards a day if you catch every cycle, in exchange for watching ads. The published reward tables cover energy, materials, XP and coins, with the large energy prizes sitting at roughly one percent. Every fifteenth draw triggers a Card Lover's Chest with XP, coins and a material.

• Draw all three boards every cycle: Nine rewards a day compounds over a month far more than any single drop.
• Disable ad-blockers: The ad has to actually play for the reward to register.
• Stack with the other daily loops: Pair it with Daily Extra Energy, the login reward and the Pixel Shop dailies in one sitting.

Gems are not on the published Lucky Cards tables, so treat this as an energy and materials engine rather than a gem source. It still matters, because energy you do not have to buy is gems you do not have to spend.

Pixel Shop daily rewards (small but consistent)

The Pixel Shop at shop.pixelfederation.com offers a free daily gift and Pixel Coins to anyone with a Pixel ID, with the daily resetting at 0:00 UTC and the coins on a 22-hour refresh. Pixel Coins are not gems and do not convert into them, but they buy shop items that reduce what you would otherwise spend gems on.

Worth knowing: a Pixel Shop link is not a gem drop. The same Pixel Federation short domain carries shop pages, portal logins and forum threads alongside genuine event links, so a link being official does not make it a reward.

Neighbor visits and god children (indirect gem savings)

Visiting neighbours' camps on the Facebook or portal versions lets you collect god children for instant energy and coins. This does not award gems directly, but it saves the gems you would otherwise spend on energy refills, which comes to the same thing over a month.

• Build an active neighbour list: The system supports a large number of neighbours, and a list of dormant accounts pays nothing.
• Visit before the timer resets: God children respawn every 22 hours, so a missed day is energy gone for good.
• Let neighbours place windmills: Each windmill pays passive energy for seven days, and the Holland System upgrade raises how many you can host.

Neighbour energy is the single most important free path for no-spend players, and it is the main reason to connect a Facebook account even if you play mostly on mobile.

Special weeks and event tokens (gem-equivalent value)

Special weeks such as Candyland, Builder, Postcard and Red Ring reward green rings, red rings, event tokens and equipment. None of it is gems, but all of it displaces gem spending: event tokens buy equipment and decorations that would otherwise cost gems, and green rings multiply material income during the doubling weeks.

Take part in the special weeks even when the theme does not interest you. Reducing your gem dependency has the same effect on your balance as earning gems, and it is far more predictable.

Passive effects and long-term gem efficiency

Spending gems on passive effects like Energy Saver, which gives a chance to recover the energy spent on a tile and upgrades across ten levels, and Experience Booster, which gives a chance at double XP, pays back over months by reducing how much energy you waste.

• Prioritise Energy Saver: Even at low levels it cuts energy waste, which is the resource that actually gates you.
• Then Experience Booster: Faster levelling means more level-up energy and more achievement completions.
• Consider the quality-of-life extras: Golem, Last Tile Finder and One Click God Children reduce tedium and wasted energy rather than paying out directly.

Passive effects are the one gem purchase that gets cheaper the longer you play. Treat them as savings rather than spending.

Common pitfalls to avoid

Most lost value in this game is not a missed jackpot, it is a small daily loop skipped repeatedly.

• Chasing expired codes: Most published Diggy's codes are months old. Follow the official accounts instead of working through a list.
• Ignoring the daily loops: Lucky Cards, Daily Extra Energy and the Pixel Shop dailies are small individually and large over a month.
• Overspending on speed-ups: Passive effects and a better-balanced camp reduce the need for them in the first place.
• Playing as a guest: Lose access to a guest account and the progress goes with it. Connect Facebook or an email-based Pixel ID.

Final tip: stack all methods

The key to free gems here is stacking rather than optimising any single source. Level consistently, clear achievements with the doubling ad, redeem codes on the day they appear, work the free Event Pass row, and run the daily loops. Over a month that adds up to a serious gem total without spending anything.
