The latest mini-game in Goddess of Victory: NIKKE, called Bubble March, will be live from April 24th after maintenance until May 15th, 2025, as part of the 2.5 Anniversary. I know there are a lot of questions surrounding this, so let me explain in detail what exactly this is.
Goddess of Victory: NIKKE Bubble March Mini Game explained
This fun little challenge is themed around a bubble-filled board game created by Little Mermaid. It brings a mix of cute visuals and tactical gameplay, where players summon bubble units to defend allied towers and take down Rapture towers.
How Bubble March works
The core of Bubble March is a tower defense-style game with a twist. You summon units called Bubbles, each with unique effects suited to fight specific Raptures. These can be summoned in multiples and upgraded to improve their power and numbers.

There’s also a Bubble Hero you can summon solo, who comes with a unique skill set. Unlocking new Bubbles and Heroes requires research, and there’s a system to boost their skills through enhancements. Each match is a race to outlast the Raptures.
If they destroy your towers, it’s game over. But if you take down theirs or beat the boss, you win. The game scales through multiple waves and difficulty settings, including Easy, Normal, Hard, and Challenge modes. The Challenge mode is especially intense, throwing endless waves your way to test your setup.
Upgrades, Traits, and Research
Before each battle, you’ll get to prepare by upgrading your bubbles and heroes. However, all upgrades reset after each stage, so planning is key.
Through research, you can unlock more characters and traits, enhancing your team’s combat capabilities. If things aren’t working out, there’s even a reset option to tweak your strategy for different enemies.
Rewards Earned

Of course, what’s a NIKKE mini-game without sweet rewards? By completing missions during Bubble March, you can collect 10 Advanced Recruit Vouchers, Exclusive Bubble March Special, Premium Stickers, and various development materials to boost your progress in the main game.
