Beat Battles Gems and Currencies

Beat Battles shows two wallets on the same HUDs: a purple gem pile and a cassette or tape counter. They sit next to each other. They do not buy the same things. This page is the currency sheet: what the purple stack actually purchases, why the cassette number is real even when it has no crate row, and which spends you should refuse on day one in a live 25-player BETA. The crate catalogue and lane-priority rolls live on Loops and Shop. Arrangement after a roll lives on remix loops. A punch list you can keep open while you decide whether to shop at all lives on the remix checklist.

Two counters, two jobs

The shop camera is the cleanest wallet shot. Gems sit in the top right as a purple diamond. Cassette or tape sits as a second counter on the same bar. In the reference shop screenshot that tape number is 110. On the stage HUD the same cassette icon returns next to the Current DJ name; the battle shot shows 703. Those two numbers prove the counter is not a shop-only decoration. They do not prove that cassette buys a Single Loop Box.

Treat gems as the spend currency for the three crates you can see. Treat cassette as a second economy this wiki will not invent SKUs for. If a later patch prints a cassette price on a crate, a deck, or a billboard boost, that belongs in a new row. Until then, do not convert 110 tape into a fake crate, and do not ignore gems because the tape number looks bigger.

Purple gems and the three crate prices

Confirmed gem rows on the crate podium:

Shop row	Price	Contents
Single Loop Box	100 gems	1 random loop
Triple Loop Bundle	250 gems	3 random loops
Full Pack Crate	1100 gems	1 random full pack

Those are the only documented gem SKUs. They expand the music catalogue: Drum, Bass, Guitar, FX, Piano Roll, Keys, and Synth. They do not print a named DJ deck, a named stage, or a Flame Machine upgrade. The Unlocks Hub is the catalogue index for those other buckets. Production level and production billboards are a climb, not a shop aisle.

Shop math you can do in the lobby

Per random loop, ignoring pack cohesion:

• Single Loop Box = 100 gems per loop
• Triple Loop Bundle = 250 / 3 = about 83 gems per loop
• Three singles = 300, so one Triple saves 50 gems on the same roll count

Full Pack Crate at 1100:

• Equals 11 Single Loop Boxes
• Equals 4.4 Triple Loop Bundles (four Triples = 1000 gems for 12 mixed loops, 100 left over)
• Is labeled one random full pack, not a loop count

The Triple is the volume buy. The Single is the cheap extra roll when one foundation lane is silent. The Full Pack is a cohesion buy for a matched kit. It is not a better Triple. Players who mash 1100 because the crate is gold are paying a spectacle tax.

What not to spend on day one

Day one is the first join through the first YOU’RE UP set. The blacklist is short and it will save more gems than any rumor code.

Do not open a Full Pack Crate. 1100 gems is a catalogue event. You have not heard which lane the crowd actually misses until you perform once. Spending 1100 before Drum and Bass exist is how a new account owns a themed pack it cannot sequence.

Do not spend gems hoping for FX. FX is last in arrangement. A random whoosh does not replace a kick. If you only have 100, that Single Loop Box is for Drum or Bass, knowing the roll is still random.

Do not sit on 250 gems waiting for a promo string. As of September 2026 there are no confirmed working codes. Check Codes when you log in, then buy according to the table. A codes page is not a wallet.

Do not convert cassette into a shopping plan. The three crates show purple diamond prices. Tape is a second counter. Inventing a cassette crate is how you stall a Triple you can already afford in gems.

Do not shop because you lost stars. A loss is usually empty Drum, late hook, or a theme miss. That is arrangement, not a crate. Run the remix checklist before you touch the podium.

Do not dump gems on a crate you will not sequence the same session. A loop that never leaves the shop ring is a wasted roll. If you are still learning the seven lanes, finish one 8-16 bar stack with starter clips first.

After the first set: a buffer, not a binge

Once you have taken a set on stage, gems become a refill, not a personality.

Keep a buffer of at least 100 so a silent kick can still buy a Single. If you have 250 and Guitar is the hole, the Triple is the efficient volume buy. If you have 1110 and Drum plus Bass already work, you may consider a Full Pack, but four Triples over time still cover more mixed lanes at 1000. Only pay 1100 when you want one style kit and you will not miss those gems next week.

Worked lobby examples:

• 100 gems, missing kick: buy the Single. Waiting for 250 while you cannot perform is a hidden cost.
• 250 gems, empty Guitar: buy the Triple. Three rolls beat one roll plus 150 idle.
• 1110 gems, finished battle kit: you can afford a Full Pack and still have 10. Only do that if the pack is more useful than four Triples. If Drum is still thin, buy Triples down to a 100 buffer instead.

Codes, Robux, and rumor wallets

No promo codes are confirmed in this BETA snapshot. Do not farm LIKE1000 strings from other music games. Beat Battles is not a tap-arrow title and it is not Friday Night Funkin. Foreign codes will not fill purple gems.

Robux or paid gem top-ups, if a Roblox prompt ever shows one, sit outside this wiki’s price table. We document the in-world rows: 100, 250, 1100. Anything sold on a third-party cheap-gems site is a scam.

Cassette and tape will keep tempting people who want a secret shop. Until a crate label shows a cassette price, gems remain the currency you budget. Production still unlocks decks, stages, and effects over time. Stars still come from other players. None of those three systems is a substitute for the purple stack, and the purple stack is not a substitute for a remix.

How gems connect to production and billboards

Official copy tells you to level production and climb billboards. That climb is playtime and finished tracks, not a gem sink we can name. Spend gems so you can actually take a set on stage. Let production hand you wearable decks and rooms. Track the public scoreboard on production billboards after you have a kit, not instead of buying the 100-gem hole fill.

A simple rule that survives a silent reprice: do not spend 1100 until Drum and Bass are covered and you can already perform. Confirm prices in the live shop if a September patch moves them. Then come back to Loops and Shop for what the boxes can roll, and to remix loops for how those clips should stack. The wallet is two counters. Only one of them currently has a till.
