Tower Defense in Your Calendar: Stop the Meetings

Every tower defense needs something worth defending. Here it is your evening. Calendar Defense hides a full tower-defense game inside a work calendar.

The premise

Meeting invites travel a highlighted route across your week, heading for your evening. You place blocks beside that route to stop them. Each block only reaches meetings within its own range, so the game is really about picking chokepoints rather than covering everything.

It is the one game on this site where the fiction and the feeling line up exactly: you are trying to stop meetings from reaching the end of your day.

Why a calendar is the right cover

A calendar already is a grid with coloured blocks marching left to right. Adding more blocks to it is the most normal thing a person can be seen doing at work. Progress is ranked on the leaderboards as a campaign.
