What can I play instead of Risk, online?

Short answer: Borderfall is a free, browser-based turn-based conquest game with the same core as Risk — reinforce, manoeuvre, roll for combat, hold regions for bonuses — but games finish in minutes rather than hours, and the factions are asymmetric. Nothing to download, and guest play needs no account.

What people usually want instead

Most people looking for an alternative want one of three things: a game that ends in one sitting, one they can play with friends who are not in the room, or one that does not require buying anything first. Borderfall is built around all three — short solo games, shareable lobby links, asynchronous turns for people in different time zones, and no purchase at any point.

Where it goes further

The board does not hold still. A game climbs through historical eras as you play it, so a match can open with legions on a classical map and end with fleets contesting orbit. There are also hand-built historical boards — Rome at its height, Sengoku Japan, Napoleonic Europe — if you would rather play one setting properly.
