Legendary crates in Basketball Legends are typically obtained by buying and opening the game’s crates in the shop, then hoping for a Legendary drop from the right case or from event/case rewards. A wiki entry for the game notes that skins and effects come from crates in the in-game shop, with rarities including Legendary, and that some cases may cost Robux.

How to get them

  1. Open Basketball Legends in Roblox.
  2. Tap the Shop button.
  3. Choose Skins or Effects , depending on what crate you want.
  4. Buy a case and open it.
  5. Keep opening cases until you hit a Legendary rarity.

Other ways people get crates

  • Codes: Some active codes grant free cases or reward crates, depending on the current update.
  • Daily rewards: The game’s reward systems can give free Coins and progression rewards, which can help you buy more crates.
  • Community updates: Players often watch Discords or videos for new case releases and event crates.

Important note

There does not appear to be a special guaranteed “legendary crate” method from the sources I found; it looks more like a luck-based drop from buying/opening cases or using reward codes that sometimes give cases directly.

If you want the fastest path, the usual move is: redeem current codes, collect free Coins, then spend them on the best case available for Legendary drops.
