Coalition and seat-allocation simulator

Bulgaria's National Assembly has 240 seats — a governing majority needs 121. The 4% electoral threshold determines which parties receive seats, but the number isn't sacred. With this simulator you can explore:

• How thresholds of 3%, 4%, 5%, or any custom value change the number of parties in parliament.
• How seats are reallocated under the Hare/Niemeyer method at different thresholds.
• Which potential coalitions reach the 121-seat majority.

The simulator uses the real regional results — not proportional scaling, but the same allocation algorithm the Central Electoral Commission applies.
