Snakes & Ladders Online

The classic 100-square race for 2 to 8 players, free in the browser. Land on a ladder's foot and climb it; land on a snake's head and slide down. One throw a turn, and square 100 has to be hit exactly, so the last few squares can take a while. Each turn has a 30-second clock. There are no decisions to make, so young children can play with grandparents on another phone, and it makes a good first game for children learning to count.

Make a table, share the five-letter room code, and friends join from any phone or laptop. Guests need no account and there is nothing to download.
