Refold
Chess on a small paper board. Your horse, crane and boat are origami, and every move refolds them into the next shape: horse to crane, crane to boat, boat to horse. Plan where each piece lands and what it lands as. Ten origami rivals, stars.

Dice Wars on a paper-craft archipelago. Attack from your territories and the higher roll wins. The twist: beaten defenders fall back into a neighbouring territory instead of dying, so only a surrounded army is wiped out. Close the pincer, then strike. Twelve maps, up to three rivals.

A tile-laying duel on a survey sheet. Two surveyors chart an island tile by tile, matching towns, roads and open land. Whoever lays the tile that finishes a town scores it and puts their name on it, no matter who built it. Leave nothing your rival can close. Eight islands, eight rivals.

Chinese checkers on a small sandstone star by a river. Race six glass marbles to the far point by steps and long hop chains. The twist: every move leaves a stepping stone that anyone can hop over until your next move. Ten river rivals, stars.

A quick duel of masters and pupils on a five-by-five patio. Move by the patterns on your lotería cards, and the card you use passes to your rival. Encore: capture a piece and you move again at once with the card you were just dealt. Ten rivals in Mexican folk-art style.

Bridge the lotus pond with lily pads before your rival links its banks. Every pad you drop sends out a ripple that pushes the rival's touching pads one spot away, unless something is behind them. Ten rivals.
