Every 2 waves you get a 30s+ ad. Annoying af. ### 1/5 — Worst game *2026-05-09* This game has nothing but ads can’t even play it ### 5/5 — The game it is really is it is easy to play and not hard at all *2026-04-15* Because I love it and it whenever I have to do my homework and I’m on break I always love playing the game ### 1/5 — Too many Ads *2026-02-22* There is plenty of ways to watch ads to earn perks. Then to throw forced adds after every level is crazy. Will be deleting cool concept but I spend more time watching ads than actually playing the game. Greed is crazy in games now a days. ### 1/5 — Ads ads ads and more ads *2025-07-03* Nice game but the ads after a level ### 5/5 — Facts about merge gun tower defense *2025-03-31* It is fun and entertaining and exciting and enjoyable ### 1/5 — Every couple seconds I get an ad *2025-03-25* Get rid of the ads good game but most of the game is just ads ### 5/5 — Great *2025-02-07* Love it ### 1/5 — Wäre nett aber so nicht *2025-02-07* Man öffnet das Spiel und wird mit Werbung empfangen…Dann spielt man eine Runde (ca.30 sek) dann darf man sich entscheiden ob man seinen Gewinn durch schauen von Werbung erhöhen will, macht aber keinen unterschied, den auch wenn die abgelehnt wird kommt … Werbung ( alle Werbetrailer Dauer übrigens länger als eine Spielrunde). Wäre ein netter Zeitvertreib für zwischendurch. Aber zum Werbung ansehe ist mir auch diese Zeit zu schade…. App gelöscht….. ### 1/5 — Ads ruin this game *2025-02-05* I played this for 15 seconds and had 45 seconds worth of ads. Don’t waste your time. ## Frequently asked questions about Merge Gun ### What is Merge Gun: Tower Defense?
