FluxSort

FluxSort is a colour-sort puzzle with a clock inside every piece. You drag glowing orbs into hexagonal receptors, and three of a colour fill a receptor and fuse — later four, then five. That part is familiar. What is not is that every orb is charging the whole time: its ring fills from white to yellow to red, and when it reaches the top the orb overloads, flips to a different colour and heats the board.

So the question is never only where a piece goes, but when. The orb you were saving for last has quietly gone red; the receptor you left open for it is now the wrong colour; and there are fewer receptors than colours, so committing one is a real decision. Too much heat and the reactor melts down. The game is about choosing which fire to put out first.

A hundred levels across five worlds — Lab, Space, Garden, City and Reactor — with a challenge level every ten and an endless mode after level one hundred. Gold orbs fit anywhere, ice orbs thaw a little with every fusion, bombs blow up and heat the board if you let them overload, and some receptors are locked. Three power-ups help: Slow Time, Purify and Magnet.

There is a daily board seeded by the date, the same for everyone that day, with rewards at seven, fourteen and thirty days of streak. It plays in either orientation, draws its own art and sound in code, and keeps your progress in your browser. No account, no ads, nothing to buy.
