One Jew is worth 50 gaza people. Make Palestinian pay Israel will liberate gaza from the hands of terrorists Y’all Palestine supporter are supporting terrorism. Israel is right Average Israelian makes 50x more money compare to Gaza citizen. 1 Isrealian is equal to 50 Gaza citizen 1 Jewish/ Israelian’s GDP > 50 Gaza people GDP 👍👍 people makes 50x more than 👎👎 people 👎👎people deserves this ### 2/5 — No *2022-01-03* This game is just not that fun as a math game. I love games in general that rely on strategy and thinking. This math game is just not too appealing. It is “fast” math but it’s not very challenging, I wish there could be more to the game as well. It seems very plain as compared to other mobile games in general. ### 5/5 — Wow *2021-11-23* amazing ### 5/5 — I done it for the shirt in mafia *2021-10-30* i'm really dumb, lowest math class but this game is good, add me on mafia (Shezzabawz1888) ### 5/5 — Fun game! *2021-10-21* Very fun game to play in my spare time and takes up much less time then other games might. Isn’t online so you can play when you have no service as well which is nice since you don’t see that much anymore ### 5/5 — Radd is totally rad *2021-10-20* Super fun and has me playing for hours on end trying to beat my high score and the scores of my friends. It’s super thought provoking making you think harder and faster than any game I’ve played before. ### 5/5 — Not bad *2021-10-13* Radd is not bad ### 4/5 — Fun *2021-10-13* It’s a challenging match-math game. It needs a little bit of a better tutorial. It took me a while to figure how to trigger bombs (just tapping them). I would also like to be able to mute the sounds. Other than that, it’s a great game! ### 5/5 — Rad *2021-10-03* RADD is rad ### 5/5 — Addicting! *2021-09-24* This is a great game! It’s very addicting, once you start you cant stop trying to get a better high score. It’s very stressful at first, but a ton of fun. Great job with this app Toast! ## Frequently asked questions about RADD ### What is RADD? RADD is a speed math game focused on addition.
