Underwater Cities

Underwater Cities gives players the opportunity to terraform the last ‘habitable’ spaces on Earth by building cities and their supporting infrastructure under the waves.  That’s the premise at least of Underwater Cities which is a hybrid tableau builder and worker placement game.  In the game, 1-4 players build tunnels, cities and other building on their own player boards by taking one of the available action slots on the main game board.  That sounds like a dozen other tableau builders out there but there are enough wrinkles and differences here, aside from the theme, which will keep this hitting the table for some time to come.


Each round of the game, every player will take three turns.  A turn starts off being a simple affair in which you choose a card to play from your hand of three cards and an action slot on the mainboard.  If the chosen card and action slot colours match, you can do the actions on both, if they don’t you’ll be limited to just performing the board space action.  This provides a significant amount of difficult decisions (this is a big plus), right from the beginning of the game.
The mainboard
However, the best part about choosing your turn actions is that at the beginning of your turn you must discard down to the hand size limit of three cards.  This doesn’t seem like it would have much of an impact of the game, but it allows for tactical thinking on other players turns, choosing which cards to discard and keep, and it means there is little-to-no downtime in between your turns.  This is no mean feat for a multi-player medium weight board game.

Like most worker placement games when a board action slot has been taken no other player can take that action.  The main game board is double-sided to accommodate 1-2 players and 3-4 on the other side.  When playing with 3 or 4 players, there are 15 actions slots on the board, 5 each in yellow, red and green which correspond to the card colours.  This means that a 3 player game will feel less congested than a 4-player game and your options to meddle, intentionally or not are limited.  In a 4-player game, however, you’re constantly re-evaluating your decision as invariably the action slot you want to take has been, probably 3 times, before it’s your turn again…thankfully this will often happen sooner than you’re ready.
2-player end game - player board
From the middle game onwards, because of the action cards that have been claimed into your tableau, there are often action combos that can be pulled off.  This is facilitated by the rule that you can resolve either the action card or board space action in the order you choose.  Where there are multiple actions within those areas, you can choose the order in which they’re resolved as well.  This means that you can often be a little a clever on your turn to maximise your benefits and doing something like this gives me at least, a great deal of satisfaction.

Finding these synergistic combos isn’t that easy though.  During your ‘downtime’ you’ll be scrambling to choose which cards to keep and which to get rid of at the beginning of your turn, choosing a card to play for your action – assuming the action slot is still available and trying to find the most optimum combo.  I never had the chance to play with anyone that I hadn’t taught the game to, but I assume that experienced players will be able to do all this as well as minimise the remaining options to their opponents.  That was not me though, I found the size of the iconography too small to see clearly in your opponents’ area.
3-player middle game - mainboard
Underwater Cities also features a variable turn order track, although it is simple, this must be one of my favourite mechanisms because nearly all of my favourite board games feature them, e.g. Brass, Dominant Species, Age of Empires etc.  However, one of the underlying rules in this game is that whenever you cover an icon up you get that immediate bonus.  In this game, if you get into the 3rd space or higher of the turn order track you will also get a bonus, which on many occasions permitted additional actions to be taken.

There are a plethora of icons on your own player board to cover up as well, giving a specific bonus, which can – and often do permit additional actions to be taken.  Which brings me onto another aspect of ‘tight’ worker placements that I enjoy.  The Euro-gamers perennial struggle to ‘feed your people’.  Not so much an issue in this game but overall resources are very tight.  There are three production rounds separating the three eras of the game, after which you’ll feel like Croesus; this will be short-lived.  However, I’ve nearly always found a way to do something worthwhile for my progress on my turn.  I never felt like I was treading water (ba-dum tish), or as last player or out of the game.
Inside the rule book


There is a traditional bewilderment of icons in this game however after the first round or two of my first I found them all to be intuitive and easy to follow without referring to the rulebook.  There is also a fantastic Player Info card which details the cost of each build and what they produce and how to conduct Production rounds.  However, as mentioned earlier when those icons are in your opponents' area across the table, their size makes it difficult to see what they are, but this can be levied against most tableau builders.
Good looking cards
Most of the other components: the cards, mainboard, metropolis tiles, player markers, city domes etc. are completely unremarkable considering modern game publishing i.e. they’re of excellent quality and just what I would expect.  However, there are a few component issues that are worth mentioning.  The player boards and player info cards are really thin card stock, almost a heavy bond paper.  The resource and money tokens seem a little odd in their design choices.  The money comes in 1s (small size), 5s and 10s which share the same size…I don’t understand why they’re not consistent and make the 10s bigger or keep them all the same size.
A random assortment of bits
However, probably the biggest issue with the components is with the 3 resource markers.  They look just like a pile of singles with a 3 in the middle.  This is better than earlier printings of the game, which didn’t have a 3 on these tokens, but it’s still not great.  Unless you keep the stacks of singles and 3s separate you can’t really tell how many you’ve got.


Aside from my component criticisms, my quibbles with this game are all fairly minor and I can easily overlook them.  The first is one of scalability.  I have not tried this solo, but the 2 and 3 player game feel quite different from a 4 player game.  I prefer the 4 player game, as long as you’re not teaching the rules, otherwise, it can drag on.  This goes against the bgg consensus that suggests 2 players is the sweet spot.
After my initial sorting
I would normally comment on the box insert in Components, but here they haven’t bothered with anything.  No cardboard trench, no ill-fitted plastic tray.  You just get all the bits thrown into a few bags and card decks and a box.  Unless that box is jammed with counter sheets and rules, like many wargames are, then this is poor practice.  Especially considering that this version comes from Rio Grande Games, one of the bigger players in the board game world.  I think my 3d-printed insert will work out just fine.
Much better, - still don't like those 3s
The vast majority of the scoring will be done in the end game, there is no way to see who is ahead or behind up until you start counting up your final scores.  This, alongside the difficulty in seeing your opponents' tableau to allow you to choose the action slots your opponents want, turn this into not much more than multi-player solitaire - not necessarily a bad thing.


With all that said, I do enjoy Underwater cities a lot.  It gives players an array of decisions to be made and there are some really smart design choices that make this gameplay quick and it is definitely on the crunchier end of the spectrum.  Discarding card(s) at the beginning of your turn makes so much sense.
3 player end game - player board
Many people have compared this to Terraforming Mars, and the main differences between the two, for me, are the board of Mars, in which players are able to have direct conflict with one another, which is a plus Terraforming Mars.  Underwater cities, pros compared to Mars, are the way in which you play and resolve cards and those synergistic combos, which I didn’t really find in Terraforming Mars.

If you like thinking games and finding optimisation strategies with a minimal amount of player interaction then I can easily recommend this game.
