FAQ

Q: How does the luck-based system work in the game?

A: Everything you do—summoning units, upgrading them, activating special abilities—is determined randomly. You might pull a powerhouse unit right when you need it, or get a quirky underdog that forces you to adapt your strategy. The idea is to embrace unpredictability and make the most of whatever you’re given.

Q: Can I choose which units to summon?

A: Nope! The heart of What the Luck? is letting go of control. When you summon, the game gives you a random unit based on chance. Sometimes you’ll get exactly what you hoped for, and other times… well, you’ll have to get creative.

Q: Is the game more about strategy or luck?

A: It’s a mix of both. Luck decides what tools you get, but strategy determines how well you use them. Even with bad fortune, a clever player can turn the tide. The challenge lies in adapting quickly to unexpected situations.
