Arenas

Each day's board is drawn as a place, the same for everyone: a biome picked from the date (never the same two days running), dressed for the season when one is on. The shape and the walls come from the day's seed; the place only changes how it looks.

Biomes

• The Hollow (cave)

  A deep cave of dark rock and teal crystals, where you eat glowing glowcaps by their own light.

• Wildwood (forest)

  A forest clearing under a thick canopy, with log walls, fireflies and sunfruit to eat.

• Sunken halls (ruins)

  Old stone courts above a drowned hall, lit by braziers and glowing runes, with jade scarabs to eat.

Seasons

• Halloween

  From 24 to 31 October, a dusk-lit world and five haunted arenas, each with its own mode and hazard.

• Winter

  All of December, snow settles on every arena, flakes fall and the food turns into wrapped gifts.

Yesterday's place is in past days.
