Pics on tiles plainer than circus game...that’s better! ### 5/5 — 🌟Support OUTSTANING🥇 *2017-05-12, version 4.3* Team CODE THIS LAB⭐️⭐️⭐️⭐️⭐️ Pleasantly surprised they pay attention to an individual customer‼️‼️‼️ All commutation & info well received by CodeThisLab. Commitment to resolve issues awesome‼️‼️ Great Mahjong for those who struggle with matching numeric or multiple tiny symbol tiles. ### 4/5 — Difficult!!! *2016-08-13, version 3.0* I have done the game on the levels. I moved along well until the last one, "The Wall". It is impossible to win. ### 1/5 — Could be a good game *2016-05-31, version 3.0* Only purchase this app if you enjoy exercises in futility I have found several flaws one particularly annoying is the active tile is under another tile and can only be seen if you tap hint many are frozen next to another tile!!!! I have screen shots to prove it. In app purchases are the same. Levels so hard there is no enjoyment. ### 3/5 — Bigger tiles *2014-12-31, version 3.0* Impossible to see on phone... Not much bigger on iPad ### 1/5 — don't waste your money!!! *2014-05-17, version 2.0* Bought 2 series in the special levels; in the seven wonders i cant even get past the first level...using hints because they are unsolvable...AFTER 3 matches it tells me that there are no more selectable tiles!! fix it or give me a refund!!!! ### 1/5 — Mis leading *2013-12-30, version 1.0* I paid the .99 to not get any ads. I still get Ads. Don't waste your money. ## Frequently asked questions about Undersea Mahjong ### What is Undersea Mahjong?
