Puzzle 375: Rugged terrain

This is a new puzzle style.


Rules: Some numbered Range rovers are placed in the grid. The objective is to drive each car as many cells as the number written in the cell, moving only horizontally or vertically. Shaded cells represent blocks of water. When a car enters water, it has to travel the entire block before leaving. Every cell is visited by exactly one car.

Puzzle 369: The space between us

Rules: Some roads are hidden in the grid. A road is a one-cell wide snake that starts and stops in a circle, and does not touch itself. A circle represents start cell, or stop cell, or a signpost. Every road must include three circles - one signpost, start cell and stop cell. Signposts cannot be the mid point of the road that they belong to. Roads cannot overlap other roads. All cells must be part of a road( No free cell can remain). Some signposts may be given.

Puzzle 366: Roleplay

This is a roleplay puzzle, one more of my ideas.

Rules: Write numbers 1 through 25, one in each cell sequentially, by moving either using king's move (orthognally or diagonally adjacent cell) or knight's move. The moves must alternate between king's and knight's. Information about the opening move is not given.

Puzzle 365: Double Nanro

Double Nanro, double the fun!
This new style is debuting here. This variation is a bit trickier than nanro. So, here is the complete set of rules:

Place two different numbers X and Y in each region, one number per cell, such that the region contains X instances of X, and Y  instances of Y. X and Y may change across regions. In the end, all the placed numbers must form a single connected group, with no 2x2 group of cells fully filled, and every number reachable from every other number through orthogonal paths. When two numbers are adjacent within a region, they have to be equal. When two numbers are adjacent across region borders, they must be different.

Edit: It just occured to me that there is a small ambiguity in the bottom-left corner. those who have solved the puzzle earlier, can use the new version below.

Puzzle 362: Jumanji

Rules: There are a few trees in the given area of the jungle. Start in one of the trees( represented by circles), write the number 1 on that tree, and find a path, numbering the trees visited in ascending order. The path can move only horizontally or vertically through adjacent cells, and all cells must be visited exactly once. The path must end in a circle.
Shaded cells cannot be visited. The path cannot visit more than 2 empty cells between two consecutively visited trees. Three or more trees  visited consecutively cannot all be in the same row or column. Some trees are already numbered.
