HexGrid Sovereign is a 2-to-4 player turn-based strategy game on a 19-hex axial grid with a central Beacon (0,0: +3 VP, +1E/round), six inner Relays (+2 VP, +1E/round), and twelve outer Frontier hexes (+1 VP/round). On your turn, spend Energy on one action: HARVEST (0E: gain +3E plus +1E per Relay/Beacon), CLAIM (2E: capture an adjacent neutral hex with 1 Shield and +1..2 VP), FORTIFY (2E: add +2 Shields up to 4 and gain +1 VP), RAID (3E: attack an adjacent enemy hex—captures and steals up to 2 VP if Shields ≤ 1, shatters 2 Shields, or triggers a +1 VP defender counter-play if Shields ≥ 3), or OVERCHARGE (5E: discharge an owned Relay/Beacon with ≥ 2 Shields for +4 VP and -1 Shield). First player to 25 VP at round end or highest VP after Round 12 wins.
