Evolving Sudoku
v0.8
Solve the bright 9×9 with normal sudoku rules. Numbers outside it don't count yet.
Each box you finish docks a magenta box of the next grid. Three docked and you warp. Blanks left behind are lost.
StreaksEvery 5 correct in a row raises your multiplier. A mistake resets it.
Second windUnder 30 seconds left, six correct in a row buys 20 more.
Every number buys time back and mistakes cost 5 seconds. The clock drains a little faster every minute you fly.
Pulse cellsAn amber ring closes on a cell. Solve it in time for bonus time.
Space junkA grey scrap in a cell. Fill it right first time for an armour plate (stops one cell of damage).
MeteorsKnock out numbers. Re-solve the red cells within 45 seconds.
MutationsMagenta numbers flood three boxes. Finish their last 2 cells before time runs out to earn a stabiliser.
Power-upsCharge as you play. Use them when they glow.
PlanetfallLand, fill the numbers shown, dig up a crystal. No meteors on the surface.
CrystalsFeed one to the sample to reveal 3 hard numbers. Some are buried in cells on planets.
Lost logsA blue diamond in a cell on a planet. Fill it to recover a piece of the story.
