New to the genre? Start with our idle games and clicker games indexes.
#1MapAttack
A real-time live strategy game — compete to control the world map.
A real-time strategy land grab on a live world map — surprisingly idle-friendly for an RTS. The May standout for us: low time-per-session, but you keep wanting to peek back at the map.
#2FlatMMO
A free 2D browser MMO heavily inspired by Old School RuneScape — skills, grinds, PvM and raids.
A 2D browser MMO that lovingly cribs from Old School RuneScape — skills, grinds, PvM, and AFK loops. Solo dev shipping in the open on r/incremental_games; the update cadence is what earns the #2 slot.
#3Theresmore
A free browser incremental strategy game — build a civilization, research, conquer, prestige.
A long-form incremental strategy game by Pier P — start as a tribe, end as an empire. Deep tech tree, armies, conquest, prestige. One of the most content-dense free browser incrementals around and a perennial r/incremental_games favourite.
#4Cookie Clicker
The genre-defining idle clicker — bake cookies, hire grandmas, and watch numbers explode.
The genre's anchor. More than a decade in and still the cleanest "open a tab and lose an hour" experience. If you've somehow not played it, fix that this month.
#5Birb
A free passion-project incremental about birbs — actively updated, community-driven.
A free passion-project incremental from hwonze, hand-tuned and community-driven. Picked up steam after Haelian's coverage and the Discord stays active — a great pick for genre fans looking for something fresh.
#6Fish Catch Idle
A relaxing idle fishing game — collect fish, earn money, unlock rarer species.
A relaxing idle fishing game on CrazyGames — cast, collect, expand. The lightest pick on the list and the one we recommend for short sessions or sneaking a few clicks between meetings.
That's our May 2026 browser shortlist. Got a browser game we should be playing next month? Submit it and we'll take a look. More monthly rankings over on the guides index.
