Peterhead missed the chance to move five points clear of the League 1 relegation zone after Forfar left Balmoor with a point.
Steven Doris levelled for the Loons eight minutes from time and it means the Blue Toon are still only two points clear of last night’s opponents.
Peterhead started purposefully in the early stages with midfielders Scott Brown, Jack Leitch and Simon Ferry having plenty of early possession.
It was Leitch who had the first effort, hooking a shot straight at Loons goalkeeper Marc McCallum from the edge of the area.
On the quarter-hour mark the home side had another opportunity when Leitch robbed Scott Robertson at the edge of the box and found Alan Cook, but his low cross from the left evaded everyone.
Then out of nothing Forfar were inches away from taking the lead in the 20th minute.
Jordon Kirkpatrick’s incisive through ball split the Blue Toon defence and Robbie Leitch raced through, but keeper Greg Fleming got enough on the winger’s angled shot to turn it behind for a fruitless corner.
At the other end a poor touch let Steven Boyd down after Scott Brown found him in space inside the area.
Fleming made another vital save to keep the game goalless three minutes before half-time.
Steven Doris’ switch of play from right to left found Bobby Barr, he drove at Jamie Stevenson and then slipped in overlapping left-back Bernard Coll, but Fleming raced out and tipped the shot over.
Kirkpatrick also curled an effort wide from long range before the break. Peterhead were the superior side in the first period, but they had no advantage at the interval.
Four minutes after the restart the Blue Toon led.
Stevenson’s long throw-in from the right was flicked on by Jason Brown and after Cook’s initial shot was blocked Boyd fired the rebound left-footed through a ruck of bodies into the net from six yards.
The Buchan outfit sensed a second goal would put the game beyond Forfar and defender Luc Bollan went close twice in quick succession on the hour mark.
First after some head tennis following a Ryan Conroy free-kick the Aberdeen loanee’s header was knocked off the line by Kirkpatrick and seconds later when Cook sent the ball back into the danger area Bollan headed straight at keeper McCallum from six yards.
Boyd twice went close to a second with a volley wide and another straight at McCallum.
But the Blue Toon were made to pay for not doubling the lead eight minutes from time when Coll crossed from the left and Doris sent a looping header beyond Fleming.
In injury time Boyd rattled the crossbar from six yards after a loose ball broke to him.
