There is no Orthodox Confession box, as far as I understand, but still confession.
Including child confession.
Many preachers in Orthodoxy will not leave because of the embarrassment of having confessed every sin to at least one confessor. Quotes
While the Penitent is waiting for the Priest to his or her confession the Penitent says, quietly, the Trisagion Prayers and Psalm 50 if there is time, and then he or she says aloud:
Penitent: I have sinned, O Lord: forgive me. I God, be merciful to me a sinner and forgive me.
When the Penitent's turn comes he or she goes forward and stands in the proper place before the Gospel Book and the Cross, which is before the Icon of Christ, and says aloud:
Penitent: O Father, Lord heaven and earth, I confess to Thee all the hidden and open sins of my heart and mind, which I have committed unto this present day. Therefore, I beg of Thee, the righteous and compassionate Judge, remission of sins and grace to sin no more.
here is the prayer
Priest: Behold, my child, Christ standeth here invisibly, and receiveth thy confession: Wherefore, be not ashamed, neither afraid, and conceal nothing from me: but tell me, doubting nothing, all things which thous has done, and so shalt thou have pardon from our Lord Jesus Christ. Lo, His Holy image is before us and I am but a witness, bearing testimony before Him of all things which thou doest say to me. But if thou shalt conceal anything from me, thou shalt have the greater sin. Take heed, therefore, lest, having come to the Physician, thou depart unhealed.
The Priest, at this point, gently and respectfully questions the Penitent concerinng his or she sins. Then the priest shares his genuine and loving and heartfelt, and possibly stern, pastoral concern and direction to the Penitent. The Penitent receives this admonishment knowing the these pastoral words come from the Good Shepard, Jesus Christ, Himself.
Priest: O Lord God, the salvation of Thy servants, gracious, bountiful and long-suffering, Who repentest thee concerning our evil deeds, and desirest no the death of a sinner but rather that he should turn away from his wickedness and live: Show Thy mercy now upon Thy servant, N., and grant unto him (her) every transgression, whether voluntary or involuntary. Reconcile and unite him (her) unto They holy Church, through Jesus Christ our Lord and to Him belongs all dominion and majesty, now and ever and unto ages of ages. Amen.
Then the Priest add this prayer, making the sign of the Cross over the Penitents head,saying:
May our Lord and God Jesus Christ, through the grace and bounties of His love towards mankind, forgive thee, my child, N., all they transgressions. And I, His unworthy priest, through the power given unto me by Him do forgive and absolve thee from all they sins, in the name of the Father and the Son and the Holy Spirit. Amen.
The Priest now gives his blessing to the Penitent
May Christ our true God, through the prayers of the Holy Theotokos, and of all the Saints, have mercy upon us and save us, for He is good and loveth mankind. Amen
This is from the Hapgood.
An Orthodox priest may certainly give a penance during a Confession, but there is no requirement that he do so. Confession & any assigned penances are both a spiritual & pastoral matter between the person & the bishop via his delegate the priest. Additionally, a person's Confession should never...Never...NEVER be discussed outside of Confession or publicly with others. A priest can & will be defrocked.
A condition for repentance is reparation of the damage done. A thief for instance should give back what he stole. Penances are described in the canons and consists in prostrations, deprivement of communion and fasting.
The canons of Saint John the Faster are the most commonly used and cover most cases.
