Chess app with king captures I am in pretty much the situation of this question: I'm trying to teach my four-year-old son the rules of chess, but the concept of &quot;checkmate&quot; is too abstract for a small child, so I want to tell him that the goal is to capture the king instead.
The problem is that I'm using an iPad app rather than a physical board (for a number of reasons, including the fact that the app will show you each piece's legal moves, so we don't have to explain all of the moving rules before we start playing).
Does anyone know of a chess app that both (1) shows legal moves (which most of them do) and (2) allows king captures (the feature I can't find)?
Antichess
Maybe Antichess is what you are looking for. The aim is to be the one to lose all the pieces first. And it's mandatory to eat. And of course kings are eaten. You can play under lichess.org such chess variant selecting a custom variant. You can see details here. But with children it's always better to play in person of course.
Legendary chess

I also recommend you Legendary chess, an application developed in Uruguay aimed for all ages and designed in a didactic way to learn chess basics step by step in a fun way with a storytelling scenario.
I don't remember exactly if there is a specific type of game where kings are eaten, but I bet you it's worth it to check the game and see.
In the site you can download the Spanish or English version. It's a Windows based application but you can always run it using wine if under Linux or Mac.
