Seven Deadly Sins NFT Adventure: Why Is MARBLEX Closing It?

Since Seven Deadly Sins NFT Adventure opened its second season on the 30th of July 2026, MBX, MARBLEX’s main token, has risen 15.4%. It went from $0.02170 to $0.02505 on the 28th of October 2026. ^[2] That same day, MARBLEX said it would close the game on the 11th of November 2026, at 11:00 Korean time. Its notice gave no reason. ^[1]

When the game closes, NFTs out exploring would go back to players’ wallets. NFTs are digital items kept in a crypto wallet. Standby characters not turned into NFTs by then would disappear. Hawk Points and unused materials would go too, with no compensation. Hiring NFTs and Demon Marks already minted would stay in wallets, but they could no longer be used. Demon Meliodas NFT staking would carry on. A Demon Meliodas NFT sale for Demon Mark holders would follow, with details in a later notice. ^[1]

What the token actually does

MBX reaches MARBLEX’s games through gMBX, a game version of the token. Players swap MBX for gMBX and back on MBX Swap, then trade gMBX for each game’s own currency on MBX Station. ^[5] Pixel TamerZ trades its TZC coins for gMBX, with a 10% fee when TZC is turned into gMBX. ^[6] Meta Toy DragonZ SAGA does the same with Magnite, at a 1% fee. ^[7] In Villains: Robot Battle Royale, turning Night Stones into gMBX costs 15%. ^[8]

More on the story

In the second season, players could claim a free character NFT and earn Hawk Points. They could also craft a Demon Mark, which unlocked a Demon Meliodas NFT. ^[2] A separate pre-mint of 1,000 Demon Meliodas NFTs sold out on the day the season opened. ^{[11] [10]}

MARBLEX closed two other game services in September 2026. Dice Go: The Showdown left MBX Station on the 13th of August 2026, and the game closed on the 17th of September 2026. ^[3] Ni no Kuni: Cross Worlds left MBX Station on the 10th of September 2026. Its Black Diamonds expired that day, and the game service closed on the 17th of September 2026. When it ended Ni no Kuni, MARBLEX said it remained committed to bringing more games to MBX. ^[4]

On the 22nd of September 2026, MARBLEX moved 8,618,440 unlocked team tokens into a marketing reserve. The project said the tokens would pay for global marketing and growth, not team pay, and that the maximum supply of MBX did not change. ^[9]
