PlayAbout this series
The Liar Series is where Sly Arcade started: short-session trap platformers set in the same corridor world, each with one kind of lie. Door Liar tricks you with doors and the HUD, Sign Liar with exit marks and arrows, Lever Liar with lever stickers, Floor Liar with SAFE floor paint, Lock Liar with keys, chests and lock labels, and Door Again (Door Liar 2) with fake save points and map pins. One rule holds across the whole series: spikes never lie. Every game has 40 hand-authored levels, a retry that takes under a second and a free level skip after five fails, so you are never stuck behind a wall of deaths. Play the series in order to see each lie introduced cleanly, or jump to the theme you like. These games include a Daily Lie: one of the game's own levels picked by your local date, and they are listed on our Daily page. Each game keeps its own progress in this browser only. If you are new, start with Door Liar for the original joke, then follow the order above; each sequel assumes you have learned to doubt the last game's favourite trick.
