In Matthew 5:3-12 (ESV), the sentence 'for theirs is the kingdom of heaven.' appears twice. In the Reorder game you have a 50/50 chance of ordering these sentences into the correct place. The game should allow the sentence to be correct in both places. It's frustrating to pick the right sentence but get the error because you picked the wrong one!
another prominent example would be Genesis 1 (in any translation) where there are repeated refrains like “and there was evening and there was morning”. Probably worst of all would be Psalm 136 where you have the same phase “His love endures forever” 26 times
