YIGE is a sliding-number puzzle: move tiles into the gap until the board is in order. It is for players who enjoy planning small sequences, building up to larger boards and returning for a daily challenge.
Made for you if
- You enjoy planning several slides ahead
- You want boards that grow from 3×3 to 6×6
- You like daily puzzles and endurance runs
Probably not for you if
- You want the traditional rectangular-block escape puzzle
- You want to fill numbers into a Sudoku grid
What you get
- 01
Let the gap guide the move
Slide a tile directly beside the empty square into it. Restore row order and leave the gap at the bottom right.
- 02
Grow into bigger boards
Five tracks offer 25,000 campaign levels. Board sizes range from 3×3 to 6×6, with separate progress for each track.
- 03
Build a daily habit
Choose a dated daily board and keep track of streaks, monthly badges and fastest times.
- 04
Spend each move carefully
Inferno gives each stage a move budget and a shared life pool. Scores and combos reward progress; hints and undo are set aside.
