Caldera

How to Play

• Everyone gets the same crater every day. It resets at 00:00 UTC, for everyone, at once.
• Nothing is fogged — every wall you can see is real. The camera follows you, then pulls back to show the whole maze once you finish.
• Scattered around the maze are vents. Each one cycles on its own clock: dormant and safe, then rumbling as a warning, then erupting — real lava spreads outward along the open corridors from the vent, further the longer the eruption runs — then cooling back to dormant. It follows the maze's own passages, not a fixed shape, so a long straight corridor can carry it much further than a twisty one. Once a vent finishes cooling, it goes dormant somewhere new — the danger map keeps reshuffling itself for the whole run, and different vents are offset from each other.
• Step into a cell that's actively erupting and you die — straight back to the start of this attempt, same maze, same vent timing.
• Vents are never required to detour around forever — every cycle has a safe window, and the maze itself is always solvable without ever needing to cross one mid-eruption.
• Find the cyan exit.
• The crater gets bigger through the week, and vents cycle faster with longer eruptions — Monday's the easiest, Sunday's the hardest. Pick a level, Beginner through Extreme.
• Use arrow keys or swipe to move. Come back daily to build your streak.
