Minimal givens must mean a good puzzle, right?

 Standard Masyu puzzle. I wonder whether the wrap-up is legible. Play

Bloom

 This is a Hinge puzzle. Shade some cells to form blocks connected by sides. Each block is contained in exactly two regions. Each block is mirror symmetric, and the axis of symmetry goes over the region border. Clues in some of the regions count the shaded cells in that region. Play online . I might have overdone the thinking in symmetry bit.

Harp

Enter a number from 1 to 9 in every cell. Numbers don't repeat in any row, column or outlined box. Numbers along the body of an arrow add up to the number in the circle. Numbers along a line ending in two circles are all larger than the number in one of two circles, and also all smaller than the number in the other. Click for web interface.

Lazy

 Wagiri rules: Draw a diagonal in every cell. Point clues count the diagonals meeting at the point. The busier cell clue belongs on a loop, the other does not.

Easy.

 

 

Bandwagon

Easy Aqre puzzle.

Rules of Aqre

Shade one orthogonally connected group of cells so that all 1x4 / 4x1 rectangles of cells are partially shaded. Clues count the shaded cells in the containing region.

Rules of Goishi

Start by picking up any stone. Continue by picking up one of the closest on any of the four cardinal directions to the most recent picked spot, and repeat until no stones are left. Consecutive picks can't be on opposite directions. If a stone is numbered with N, then it is the Nth stone picked.

 The addition of indexes makes this the GP, not the standard formulation. The automated solver won't impose the restriction.

Rules

Fill all questionmarks and some empty cells with numbers, such that all numbers are orthogonally connected into one shape. Same numbers do not share cell sides. A number sums the empty cells in its row and column directly visible from its position without going over another number.

Troll entry

Rules of Nurikabe. Difficulty: trolling, obviously.

Flood

Rules of Yajilin. There's a flood of average Yajilin on the internet, let's contribute. Slightly above easy.

 

 

Doggy

Rules of Scrin: Shade cells to form rectangles. Rectangles don't share any cell side, but each rectangle shares corners with exactly two other rectangles. In this manner, rectangles enclose a single orthogonally connected unshaded area. All clues must be covered by rectangles, but no rectangle may cover multiple clues. Clue numbers indicate the area of its covering rectangle in cells.

Written to familiarise me with the genre, I don't really think it's a pleasant solve.
