Blooms – a strategic territory game for two players

 

blooms-example-fast-small

Blooms is a territory game for 2 players, played with stones on a hexagonal board. I recommend new players start on this board (PDF); then try larger boards as you gain experience (make printable boards here – players familiar with Go should probably start on a board with 5 spaces on each side). Each player owns stones of two different colors, so there are 4 colors in all.

Definitions

  • Bloom: a bloom is an entire group of connected stones on the board of the same color. A single stone (unconnected to others of the same color) is also a bloom.
  • Fenced: a bloom is fenced when there are no empty spaces adjacent to any of the bloom’s stones.
  • Territory: a lone empty space or entire connected group of empty spaces is said to belong to a player’s territory if all stones adjacent to all empty spaces in that group belong to that player.

In the above example, there are 2 blooms of each color (8 total). None are fenced, since each has at least one adjacent empty space. One player plays red-yellow, the other grey-black. Red-yellow is the only player with territory (in the upper right); no other empty spaces or groups of empty spaces are adjacent to only one player’s stones.

Rules

  1. To start, Player 1 places a stone of either of her colors on any empty space.
  2. From then on, starting with Player 2, the players take turns.
    • On your turn, you must place 1 stone of either of your colors, or 1 stone of each of your colors. Alternatively, you may pass your turn.
    • You can place your stones onto any empty spaces, with one restriction: you must place them such that, at the end of your turn (after you’ve captured enemy blooms – see below), none of your blooms is fenced.
    • After placing your stones, capture all fenced enemy blooms. Return the captured stones to your opponent.
  3. The game ends when one player resigns or when both players pass consecutively. In the latter case, your score is the number of stones you have on the board plus the number of spaces in your territory. The player with the highest score wins. In the event of a tie, the player who passed first in the game wins.

Note: when players have experience, most games will end in resignation, as it will be easy to see what the final scores will be well before the game actually ends.

Quick Comments

There’s a story behind this design, but I have to save the telling for another day.

Though Blooms is Go-like, Komi isn’t required in Blooms because there’s no stone advantage between the first and second players as there is in Go.

In addition, I doubt Ko rules are needed. As far as I can tell, Blooms is soft-finite on boards large enough so that at least one living Bloom is inevitable. A soft-finite game is one where cyclical positions are possible but will only happen if neither player is trying to win.

Below is a slowed-down version of the gif at the top of the page, in case you want to scrutinize the example game more. In that game, one player plays grey-black, the other red-yellow. Grey-black wins narrowly (close games are rare on small boards, so far – it’s more common for one player to collapse entirely).

As you can see, you can have a significant material advantage and still lose.

One thing you can’t see is that the mix of colors at the end varies from game to game. Games played side-by-side can look pretty. I like that.

There’s a nice discussion of Blooms on BoardGameGeek, here.

Try Blooms for yourself

You can play Blooms against a weakish AI, using Stephen Tavener’s AiAi system (download here). To run it, you’ll need Java and you may need to change your security preferences. You’ll get a bunch of zipped files in the download. The file to run is “ai ai.jar”. Once opened, load Blooms by going to: File –> Choose Game, then select Blooms.mgl. You can change the AI settings from the AI menu.

Kickstarter?

There’s a chance I’ll make a boxed version of Blooms through Kickstarter. Sign up here to be alerted if it happens. The more people sign up, the more likely I am to do it.

Thanks to…

  1. Something I find oddly pleasing about the 3 Definitions.
    Bloom is defined in terms of one colour.
    Territory is defined in terms of two (allied) colours.
    Fenced is defined in terms of four colors (i.e. all the colors).

    3 notes:
    The Three Definitions sounds like a really nerdy music trio.
    Nick, your current headshot is terrible.
    I have a really bad memory (and can’t remember the 3rd note I had in mind).

    1. Why thank you! I guess I need a new head shot. What’s bad about this one? (so I don’t repeat the same mistake)

      1. You seem to consist entirely of forehead. That may be accurate, or the look you’re going for. But you could add a smile, fiendish grin, or other endearing expression.

        Blooms is a very impressive design, especially in terms of decisions/rules ratio. There’s a lot behind that forehead!

      2. Unfortunately, I DO consist almost entirely of forehead. But yeah, I can see that my expression maybe isn’t the greatest. I’ll work on it.

        And thanks very much about regarding Blooms. I haven’t expressed much of an opinion about it here, but I do have one. I’ve been saving it for a designer diary to be written later, but suffice it here to say: the game is very important to me, and I’m glad you see something in it.

  2. G’day Nick. I’m always interested to know the process whereby you monster creatives happen upon your brilliant ideas. Perhaps in a reflective mood you might let us know the process you went through with Blooms. Do you look to innovate from another game, do you like a way something else plays and look for a mutation that survives Darwin’s tests? Wondering?

    A neat little abstract is currently entered in the 9 card BGG contest is Orchard, a design by the prolific and pretty talented Mark Tuck. Have you had a look at it? If so, how do you rate it? Those who SAY they have played it and come in with atrociously high scores must have Pinocchio’s problem, I’m hard pressed to get halfway there.

    Anyway, Congratz on Blooms, although even before I try playing it, it has me bothered. I woke in the wee hours with visions of how to make nicely coloured and ornamented pieces for it. Could I CNC plaster of paris or maybe resin with glitter in it, stained glass effect?? – whatever, The sheer prettiness of Blooms is going to be fun to play with.

  3. Thanks Garry! I’m writing an essay about how I came up with Blooms, but in the meantime, take a look at this: https://nickbentley.games/2014/05/12/the-100-10-1-method-for-game-design/

    I’m deliberate in cultivating my own creativity, and I believe it’s possible for others to do the same. The essay at the link above discusses how I’ve gone about it. It’s also the most-read essay at my site and it seems like lots of people get some use of it.

    I have couple of ideas for pieces: the most fanciful is to embed different colored flowers in transparent resin. That would be astronomically expensive, so if this ever goes to Kickstarter I might opt for another option.

    I haven’t seen Orchard, but I’ll check it out if I get some time (probably not this week).
