Slap Battles: How to Get the Sand Glove and Estival Heatwaver Badge

The Sand glove is the headline reward of the latest Slap Battles update, and it sits behind the Estival Heatwaver badge rather than a slap price. You earn both by clearing a hidden Four Seasons minigame reached through the cabin area, and the update also ships a fresh redeemable code called Sandcastle.

Quick answer: Go through the lobby portal to the cabin, click the “The Four Seasons” books on the shelves behind the counter to open a tree portal, enter it, and finish the minigame. Completing it awards the Estival Heatwaver badge, which unlocks the Sand glove.

Sand glove stats and ability

The Sand glove has a passive-free active kit built around one button. Its ability, Beach Day, triggers with the E key. Here are its pedestal numbers.

How to unlock the Sand glove and Estival Heatwaver badge

The whole unlock runs off the badge. You never buy the Sand glove with slaps, so the only task is finding the minigame and finishing it.

From the lobby, enter the portal that takes you to the cabin area. This is the interior space where the seasonal content is staged.

Walk behind the counter and look at the shelves. Find the books labeled “The Four Seasons” sitting among the other items.

Click the books. This reveals a tree with a portal built into it, which is the entrance to the minigame.

Step into the portal to load the minigame instance.

Complete the minigame. On success, the game awards the Estival Heatwaver badge and the Sand glove becomes available.

How to confirm the unlock worked

You will see a Roblox badge notification for Estival Heatwaver once the minigame is cleared. After that, head back to the lobby and check the glove pedestal. If the badge is registered, you can click the Sand glove and equip it, then use Beach Day with E in the arena.

If the glove still shows as locked, the badge did not register. The most common reason is leaving the minigame before it fully completes, so run it again and finish it in a single attempt.

New code: Sandcastle

The update introduces the code Sandcastle, which grants in-game rewards toward your slap count. Codes are case-sensitive and can expire without warning, so redeem it while it is active.

Launch Slap Battles and click the Twitter/X icon on the left side of the screen.

Enter your X username if prompted, then type Sandcastle into the code box exactly as written.

Press Redeem. A confirmation appears and the reward is applied to your account automatically.

Alongside the Sand glove, the patch adjusts several existing systems and reworks the look of multiple gloves.
