Octiles

 A Dale Walton's game from 1984 published by Kadon.

Each player starts with five counters on the initial positions. There are also 18 tiles,

 

all eighteen tiles

Each player must move their counters to the circles on the other side of the board.

At the beginning the board is empty, and there are no paths to travel. The tiles are shuffled and stacked.

On his turn, 

1. a player takes the top tile from the stack and places it on the board (adjacent to one of her pieces). The tile may replace an existing tile, which goes to the bottom of the stack.
   
2. then the player moves one of his pieces over that tile, and eventually others, travelling thru a connected path. The path must end in an empty middle circle. Pieces cannot stop at the adversary final circles (i.e., their initial positions for a two player game).
   

When all tiles are used, all remaining moves will imply a tile replacement (the removed tile is then used by the next player).

Notice that when paths cross, that means bridges not road blocks. Paths can also follow the paths printed onboard.

When a piece reaches one of its final circles, it can no longer move. 

A player can pass, but it is illegal to have two passes in a row.
