Every player draws a vector on the
field, with the following rules :
1. Horizontal or vertical vector, with length 1 (the distance, between
dots, in same line or column) with arbitrary direction, if the vector
doesn't intersect any existing one.
2. Vector, whose is a sum of two existing connected vectors (non marked
*), with joint
vertex, if :
- is a "discreet" (i.e. is drawn from dot to dot);
- doesn't intersect existing vector;
- must be joint with both vectors, whose sum is it (all 3 vectors
must be joint, each to each);
- for preventing multiple usage of already used vectors, mark the
vectors, whose sum is it *.
The winner of the game, is the player, who makes the last possible move.
* This is a rule of multiple usage. The players can choose to play with
or without it. I reccomend to play with this rule.
Examples of valid
The game may look i little complex, but actually the rules are very
simple. Here are some examples of VALID
correct sum of two vectors
another correct sum of two vectors
one more correct vector - sum of two orthogonal vectors
This is a legal move with the latest game rules.
the longest blue vector is a sum of the two red vectors
Examples of invalid moves :
Here are some samples of INVALID
in the game - the GREEN
shows the invalid move :
the green vector intersects the existing blue vector.
the green vector is a sum of the blue and red vector, but only in math.
In Veptheca, source vectors must have joint vertex.
another incorrect move in Veptheca - the sum vector doesn't have joint
vertex with the first vector.
Game example :
These are animations, which shows a sample games on a minimal
playing-field (3X3) for two players. The moves are in different colors
just for clarity. The red player begins the game :
Sample game with the rule of multiple usage.
Sample game without the rule of multiple usage.
