Bit of a boardgame design challenge here. Can I make a game using thrown away bits of another game? Number of Players: 2-5
Type of game: Abstract strategy tile laying

• 20 square counters from the centres of the Colosseum arena pieces which consist of-
  • two blank counters with a light and dark side in 5 colours
  • two arena stand counters with a light and dark side in 5 colours

Board Piece (BP) - A blank counter of your colour.
Fortification (F)- An arena stand counter of your colour.
Mobile mode - A counter that is light side up.
Attack mode - A counter that is darker side up.
Touching - An edge to edge laying of counters.
Flipping - Changing the mode of a counter by turning it over.

Each player takes four counters of the same colour - two Board Pieces and two Fortifications.
Note: All pieces initially placed are done so in Mobile mode.

1. Placing Board Pieces
   1. One player places their first (BP)
   2. Each other player places one (BP) such that it touches one other player's (BP) - but does not touch any other player's (BP).
   3. Each player then places their second (BP) such that it touches their previous (BP) but no other player's (BP).
2. Placing Fortifications
   1. Each player places their first (F) such that it touches one of their (BP)s but no other player's (BP).
   2. Each player places their second (F) such that it touches one of their (BP)s or the previous (F) but no other player's (BP) or (F).

Each turn consists of a player making two actions. The two actions made can be any combination of-

• Moving a Mobile Board piece or Fortification
• Moving an Attack Board piece or Fortification
• Flipping a Board piece or Fortification

• If moving the counter will not disconnect any other counters (i.e. it will still be possible to trace a path from any counter to any other counter through touching edges)
• If the counter you wish to touch has at least two exposed edges.
• If the counter you wish to touch is not fully enclosed by other counters.

Move the counter and any other counters on top of it to touch the other counter.

• A counter in Mobile Mode cannot move on top of another counter, but can carry other counters.

• If the counter has no other counters on top of it.
• If moving the counter will not disconnect any other counters (i.e. it will still be possible to trace a path from any counter to any other counter through touching edges)

Move it to touch a counter next to it or move it on top of a counter it is already touching.

• It can move only 1 space.
• It can move on top of another counter.
• If it is a Fortification piece and you are moving it on top of another Fortification piece belonging to a different player - you capture that piece.
• Moving a Fortification piece onto a stack of other counters will only effect the top most counter, and only then if it is a Fortification piece.

• If the counter has no other counters on top of it.
• If the counter had no other counters beneath it.

Turn the counter to its other side.

• It stays in its current position.

The game ends when only one player has any Fortification pieces left.
