Thrillaroo

Go as a quiet practice under a breathing aurora: pearl and indigo stones on a soft grid, captures that fade like breath on glass, and a lotus at the foot of the screen that opens every section. The flower, from the roots up:
Roots · The rules
Take turns on the crossings, Black first. A group with no empty neighbour is captured; ko stops an instant retake. Two passes end the game, and the count is stones plus surrounded points, with 6.5 komi for White.
Stem · Journey
Eight chapters on a winding path, each with its own master and a few lines of story: Mira in Pebble Garden, then Tavi, Oren, Sela, Ines, Haru, Lune and Elder Sol at Moon Gate. The grid grows from 9×9 to 13×13, the partner grows stronger, and in two chapters you take White. Finish ahead to open the next.
Leaves · Practice
A calm game with a partner bot, Breeze, Tide or Stillness, on 9×9 or 13×13 with the colour you choose. Or hand the phone to a friend sitting with you.
Petals · Stillness
Twenty-four capture puzzles in gentle, steady and deep sets, with a hint and a fresh start for each.
Seed pod · Insights
One ring shows the share of games you finished ahead. Tiles count chapters, games with friends, puzzles, captures, days practised and milestones; eight milestones track your progress and the last 20 sessions are kept.
Still water · Settings
Haptics, the way of the stones and a reset. The aurora behind every screen drifts and breathes; Background animation in Settings turns it into a still image.
