The full list, and how each one unlocks.
Achievements are one-off unlocks that recognise something you did. There is nothing to claim and no list to check off manually: after every game, the game tests each locked achievement against that game's result and against your lifetime totals, and anything newly satisfied unlocks on the spot with the date recorded. One (winning a best-of duel without dropping a round) can only be judged across a whole match rather than a single round, so it is checked again when the match ends.
They are stored with your account on the server, not in your browser, so they follow you to any device you sign in from. That also means the same rule as Droplets applies: a game played while the server is unreachable unlocks nothing, because there is nobody to record it. Achievements are cosmetic recognition: none of them gates a mode, an item or anything competitive, and the same is true of the account XP and account level you accumulate alongside them.
Some unlock from a single game, and some are lifetime milestones that accumulate quietly across every mode you play. All rumble flavours (classic, Mayhem and Loadout) count towards the rumble achievements.

The first handful arrive on their own while you learn the game. After that, the fastest route through the list is a spread of modes rather than a single one: most solo modes have an unlock of their own, the duel and rumble entries need versus play, and the lifetime totals build up regardless of what you play. If you are new, work through How to Play first: most of the single-game achievements are just the game's core skills (a Quad, a Twist, a chain, a perfect clear) happening for the first time.
The multiplayer entries are covered in Duels & Rumbles, and the item ones in Mayhem & Loadout.
