The Lost City
A mystical stage run with boosters and, by design, no clock anywhere.

The Lost City makes a deliberate choice and states it plainly: no time restrictions anywhere. Every stage is yours to study for as long as you like, which turns the run into a set of puzzles rather than a set of races.
That changes what the boosters are for. In a timed game a booster buys seconds; here it buys a way through, so the only question is whether the board in front of you actually needs one. The colourful field explosions from three-in-a-row clears are generous enough that many stages do not.
The mystical stages give the run its variety, and the absence of pressure makes it a reasonable recommendation for anyone who finds the genre stressful rather than relaxing — the game has removed the exact thing that usually causes that.
Controls
Click or tap two adjacent pieces to swap them.
How to Play
- Take as long as you like reading the board — nothing is timing you.
- Swap two neighbouring pieces to hit three in a row and set off the explosion.
- Use booster effects on stages that genuinely block you.
- Work through the mysterious stages at your own pace.
Tips & Tricks
Use the absence of a clock properly: before each move, find your second move as well. On an untimed board that costs nothing and turns a run of single clears into a sequence of chains.
