I believe I have solved this puzzle, but the 1^ cage in the middle is being flagged as incorrect with 1,5,7,7 as its contents -- integer overflow perhaps? |

Same. And while all other puzzles today have been solved a number of times, the counter to the left of this one reads "(solved 0 time(s) so far)". |

Same problem. Possible overflow in the calculation of powers depending on the sequence followed by the software, since (5 ^ 7) ^ 7 = 1,776... e+34. Consequently, the correct combination c3 = 7, d3 = 1, c4 = 5, d4 = 7 is not accepted as valid giving the red indication in cage 1^. At this time still 0 solutions as observed by bram. Suggestion: To modify the operation to 20+, for instance. |

Glad to see not just me - 1^ last cage I completed and was going crazy going over rest to make sure hadn't made any errors |

Yes, this was reported by many people, seeing it only now (8.09am here), my first guess is also no overflow in the generator/solver, but overflow in the code that's running in the browser. Edit: this turns out to have been the case. The problem has been "solved" now by a hack: if a cage has the ^ operator, and 1 as the result, and there's a 1 in there somewhere, it is approved.. (should work ) |

There are other cases that could still cause trouble. E.g. for an "8^" cage with 6 elements, you could have 8 = 2^3^1^7^7^7, but the 7^7^7 would cause an overflow. |
