Each achievement has conditions that must be met before they are earned. Some are very simple, and some are significantly trickier. You may have to Big Crunch or start a challenge before attempting some of the harder ones.

You will receive a x1.5 multiplier to all dimensions for each completed row. In addition, some achievements have their own rewards.

How the antitables have turned Get 8th Dimension multiplier to be highest, 7th Dimension multiplier second highest etc. Reward: Each dimension gains a boost proportional to tier (8th dimension gets 8%, 7th gets 7%, etc.) There are multiple stages of the game you can get this and some where it becomes impossible.

It can be gotten early by minimizing IP, then buying only enough of each dimension to exceed the previous, then sacrificing.

Later, the boost from the ID8 reward combined with post-eternity multipliers will make the non-first dimension multipliers high enough to not need to worry.
