Mine Antarctica Mining Luck — Garden and Group Bonuses

What is Mining Luck?

Mining Luck is the game’s stated bonus that improves your digging results. The official game description names exactly two sources, and both are free — no Robux required:

1. The garden. The description says: “Place crystals in your garden for MORE digging luck!”
2. The group. “Like & join the group for +1 Mining Luck!”

Exactly how much each crystal placement adds is not published by the developer. Any concrete percentage you see on other sites is a guess. What follows is what is officially known and how to use it.

Source 1: the garden

The garden is the game’s persistent luck bank. You place crystals into it instead of selling them, and they keep paying out in luck instead of Cash:

• Which crystals count is not published. The description says “crystals”, so the safe reading is: place what you can spare — duplicates and low-value finds that you would sell anyway.
• Placement is permanent as far as anyone can tell. No community source documents an option to remove crystals from the garden. Treat every placement as final — park crystals you do not need to sell.
• It compounds with everything else. Garden luck applies wherever you mine, in every zone, at every altitude.

The garden is the reason to think twice before selling everything. One or two spare crystals per run parked in the garden is a common pattern among players who keep their luck climbing. For what each crystal weighs before you place or sell it, see the crystal guide.

Source 2: the +1 Mining Luck group bonus

This is the only officially quantified luck bonus in the game:

• Like the game (thumbs-up on the Roblox page) and join the PolarMine Games group — together they grant +1 Mining Luck.
• It is effectively permanent and free. There is no reason to skip it, and it is the very first thing to do in any first session.

The group passed 128,000 members in late September 2026, which tells you how many players have already claimed it.

What about luck from other places?

You may see claims about luck from rebirths, game passes, or paid boosts. The official description lists only the garden and the group. The community has also reported boulders with unusually high luck labels — for example video titles mentioning “50%+ luck crystals” — but those are unverified community reports, not confirmed mechanics. If a future update adds new official luck sources, this page will be updated after we verify them in the official channels.

Until then: keep the garden stocked and keep the group bonus — the two luck sources that are written in the game’s own description.

Luck FAQ

Other pages answer the same questions in passing; here is the concentrated version:

• Does luck affect crystal weight? Not officially stated. Luck improves digging results; the weight of what you dig is a separate property — see selling crystals.
• Can you remove a crystal from the garden? No method is documented. Place only spares.
• Is +1 a big deal? It is the only officially quantified luck number in the game, and it is free — take it. How much +1 is worth in practice is not published.
