Classic
Runs and sets against the clock
The original game from 2014. Drag bars into sets of one color or runs of neighbors on the color wheel, then flick them up to clear them. Clears add time, and every quest you finish multiplies your points.
Levels
Sort gradients, one after another
Each level deals a gradient out of order. Drag the bars into a smooth sweep of color and flick it away. Solving adds time, and every level brings more bars and closer shades.
Clear
Clear each row in as few moves as you can
Each puzzle deals a row with Classic's rules. Clear every bar in as few drags as you can. Par is the fewest it can take, and matching or beating it scores more points before the clock runs out.
