数独（shù dú）是源自18世纪瑞士的一种数学游戏。是一种运用纸、笔进行演算的逻辑游戏。玩家需要根据9×9盘面上的已知数字，推理出所有剩余空格的数字，并满足每一行、每一列、每一个粗线宫（3*3）内的数字均含1-9，不重复。 数独盘面是个九宫，每一宫又分为九个小格。在这八十一格中给出一定的已知数字和解题条件，利用逻辑和推理，在其他的空格上填入1-9的数字。使1-9每个数字在每一行、每一列和每一宫中都只出现一次，所以又称“九宫格”。 数独游戏风靡全球，解开它需要你的是推理与逻辑，简单的规则适合不同年龄段的玩家。希望大家会喜欢。

Verdict
The clearest difference is in-app purchases: BrainBay at none against 天天数独's 1. BrainBay also leads on update cadence (every 3 weeks vs every 2 months). 天天数独's advantage is iOS requirement (9.0 vs 14.0). On price, ads and device support there is nothing between them.
