The review of Charles Timmerman’s funster Hard to Extreme Sudoku continues with Extreme 46. It’s  entertainingly advanced.

Extreme 46 has its moments.  The basic trace is spread across the page with 3-fill after 3-fill. Two unusual events occur in box marking: three clues after the bypass, and the N 5-slink claim.

Here is the naked triple in c4.

Right out of line marking, a testimony to construction fun versus anxiety inducing search, a Rube Goldberg 275-wing. The grouped 7-chain wink places the third member of the toxic set out of sight of any victim, but hey, it’s an ANL. Celebrate.

On down the XYZ map, a regular 471-wing with an irregular victim. 1r3c1 sees the third toxic 1 via 1-chain.

That removal enables one of those long, rambling XY nice loops through the bv patch. The many victims include the single triumph of the Rube Goldberg 275-wing, but we don’t mind.

The follow up includes a shift of the nice loop to make another removal. The resulting naked pair grows the bv patch.

When I catch my breath and apply the crayons, blue is wrapped in c2, and the green army marches in.

Next time, we do funster Extreme 60 and 74. If you’re playing along, its mostly about comparing basics. The starting grids are below, 60 left and 74  right.

A new page on finned fish is up in the Guide.
