Hexadecimate Rules

An overview of the rules of my first board game

Number of players: 2

Duration: 20 mins

Items Needed: Hex Board; 11 Blue units, 11 Red units, and 4 Purple units; a standard deck of cards

Each player starts with 7 units.
Arrange the board like so:
Play order is determined by card draw; whoever draws the higher card goes first. Reshuffle the deck after.
On their respective turns, each player moves their units a number of times equal to their total units. Moves can be distributed in any way, but players must use every move each turn.

e.g. On your first turn, you have 7 moves, one for each unit.
A unit can attack an enemy unit when it occupies a space adjacent to it. This attack can be augmented by up to 2 other adjacent ally units, at a cost of 1 move per augmentation.
Defense can be augmented in the same fashion.
During an attack, the attacker draws a card for each unit used, keeping the highest. The defender then does the same, and whoever has the highest card wins. Ties go to the defender.

e.g. Each player has a unit in an augmentation space. When Red attacks Blue, they can each choose to use that unit to augment their attack/defense. Attacking with additional units costs 1 move per additional unit used.
After a successful attack, your unit moves into the space the defending unit once occupied, and that unit is destroyed.
After a successful defense, the attacking unit is destroyed.
The deck should only be shuffled after it has been exhausted.
The first player to eliminate the enemy army is victorius!
