The description from Board Game Geek:
Canal Mania is a game about the great canal-building era of the eighteenth and nineteenth centuries that captures the feel of the period and gives players plenty of decision making in their attempts to complete some of the most famous British canals.
Players will engage brilliant engineers such as James Brindley and Thomas Telford in their efforts to create canals linking emerging manufacturing centers, thereby providing the waterways that supplied the goods generated by the Industrial Revolution.
The goal of this game is to have more victory points than your opponents. You gain victory points by building canals (with 0-3 victory point for each hex and 2-8 victory points for the contract) and moving goods through canals (1 for each town you visit, including the first one).
Each turn has 3 phases. In each Phase you can chose one action:
- Take a contract from parliament
- Exchange engineers
- Discard the five face up building cards
- Pick up three face up build cards
- Build tiles
- Move one good token
Any Phase Alternative:
- Draw one card from the top of the build deck
I think one of the keys to doing well in this game is not getting fixated on early one, two, and three point grabs. This includes both moving cargo boxes one canal segment and utilizing non-stretch canal hexes when unnecessary. Certain building restrictions will require some flexibility during canal construction and conservation of canal hexes but finding yourself late in the game unable to build a route because of a lack of canal hex types can leave you out of the running when it is most crucial, particularly if that contract is going to tie together some lines and allow for a big score to put you over the top.
Rather than moving a lot of single segment cargoes early on, I think it is more worthwhile drawing that extra build card in the third phase, even if it turns out not to pay off every time. Grabbing those extra build cards in the third phase might help avoid missing too many opportunities during phase two on a subsequent turn not building.
Perhaps contrary to this advice, I also think it's important to look for chances to strategically switch engineers. It can save a lot of unnecessary drawing of building cards during the first phase on various turns.
Furthermore, be careful not to choose contracts that wind up having you loop back around on yourself. The requirement to take the shortest route when moving cargo if you have two routes of your own to choose can be a costly loss of victory points.
*Edit* We missed two rules the first time through. We didn't realize you could not pass any color twice when fulfilling a contract nor that you cleared the board at the end by fulfilling unfinished contracts if possible. These may well have simply offset one another in our case.
Obviously, you have to play with the cards you get but I think these strategies in combination can help build toward a healthy end game.
