Three rules, one solution, no guessing. Watch a full board get solved in a minute, then take the five moves below — in each diagram the shaded cells are what you know and the rest is what follows.
The three rules
Half bees, half bloomsEvery row and every column holds the same number of each — three and three on a 6×6 board. This row is complete.
Never three in a lineTwo alike may sit side by side; a third may not — across or down. Three bees: one has to go.
=×
Signs link neighbours= means the two cells match, × means they differ. Tap a cell once for a bee, twice for a bloom, a third time to clear.
Five techniques
1 · Cap the doublesTwo bees side by side can't take a third, so the cells on both ends of the pair are blooms.
2 · Fill the gapA bee, a gap, a bee: a bee in the gap would make three, so the gap is a bloom.
3 · Count to the limitA 6×6 line takes three bees. Once three are in, every empty cell left in that line is a bloom.
=
4 · An = pair is a double in waitingThe two cells joined by = match, so they behave like a double: they can't be the same as a neighbour on both sides. With a bloom on each side, a pair of blooms would make four in a line — the pair is bees.
×
5 · A × pair spends one of eachThe × pair holds exactly one bee and one bloom — you don't need to know which way round. That bee is the row's third, so both cells after the pair are blooms.
