The Giants thought they had stolen the game when it turned on a trick-pass touchdown from Odell Beckham Jr. in the third quarter.
The Bears saved their own trick for the final seconds of regulation.
On their own version of the “Philly Special,” running back Tarik Cohen threw a 1-yard touchdown pass to Anthony Miller as time expired, sending the tie game to overtime.
The game-winning points were much less thrilling.
In overtime, the Giants got the ball first, and Aldrick Rosas booted a 44-yard field goal before their defense finally got a stop to secure a 30-27 win over the Bears on Sunday at a soggy MetLife Stadium.
