Southern Africa
Zambia & Malawi
Nsolo (Zambia, Malawi) and Nchombwa use Tsoro-style sowing on a 4×8 board, with one important twist: after each capture, you also remove an equal number of additional counters from anywhere on the opponent's side.
Setup
Two seeds per pit, but each player's rightmost inner pit starts empty.
Capture
Take the opposing inner pit, then remove the same number again from anywhere on the opponent's side.
Draw
A repeated board position is treated as a draw.
