Keyflower strategy

Logic Level 3

In the board game Keyflower , a mechanic of the game is to place workers on a tile to activate the tile's effect. A player that wishes to activate the effect places a number of workers on the tile. If any player wishes to subsequently activate that effect again, they must place more workers than the latest one previously put in. Additionally, a tile may not have more than six workers.

Thus, as an example, a player may place one worker on the tile; another player may subsequently place two more; another player can place three more; after that, there are six workers on the tile, so there cannot be any more use of the tile.

It has been suggested that the rule that "a tile cannot have more than six workers" is reworded to "a player can only place at most three workers on a tile at a time". Are they equivalent, or just strategy-wise equivalent (equivalent if players are playing perfectly), or even not at all? Assume that having extra workers is never a detriment to a player.

  • A. They are equivalent.
  • B. They are not equivalent, but they are strategy-wise equivalent.
  • C. They are not strategy-wise equivalent.

They are not equivalent, but they are strategy-wise equivalent.

They are not equivalent, since in the original wording of the rules, a player may put four or more workers at a time (for example, they may put six workers on an empty tile).

However, they are strategy-wise equivalent. Note that whenever a player places three or more workers at a time, that tile is now blocked and no player can place more workers there. This is because if a player wants to do so, they must place four or more workers, but then there would be at least seven workers, breaking the original rule. Thus it's enough to place three workers to block a tile. Since having extra workers is always a good thing, it never makes sense to place more than three workers on a tile at the same time.

Moderator note:

What is a reason for games to define things in way that is different from the strategy-wise equivalent definition?

Which is easier to understand - "No more than 6 workers of any type can be on the tile" or "You can place at most 3 workers on a tile at a time"?

@Challenge Master: I'm not sure either; personally I'd go with "you can place at most 3 workers on a tile at a time". The former is an interesting wording though, that isn't found in many other games, and it makes a nice little problem.

Some people, like myself, are not familiar with the rules of keyflower. Rather than having to look up keyflower and learn the rules, could you make it clearer in the question that a player may place any number of workers on a tile up to 6. You never say it is impossible, but I assumed that it was from the example. (If it were impossible then they would be equivalent). The mere fact that you felt that it was necessary to include the rule in your answer in order to validate it gives the impression that the question was missing vital information.

I did say that rule in the problem:

A player that wishes to activate the effect places a number of workers on the tile.

There is also the rule that a tile cannot support more than six workers.

You are right, I misread. I tend to read too quickly and miss the subtler points
