How to play SinkIt

Deploy a five-vessel fleet, locate the hostile formation, and sink every enemy vessel before your own fleet goes under. Each turn gives you one tactical action.

1. Prepare your fleet

Drag each vessel from the manifest onto the 13 × 13 ocean grid. Ships may be horizontal or vertical, cannot overlap, and must remain inside friendly waters. You can drag a deployed ship to reposition it before the engagement begins.

2. Choose a weapon

During your attack window, select a weapon from the Arsenal and target enemy waters. The Missile is always available; advanced weapons have limited uses and larger impact areas.

Missile

Attacks one grid cell. A strike reports a hit or miss and ends your turn. Missiles are unlimited, but previously attacked cells cannot be targeted again.

Scout Drone

Scans a 2 × 2 area once per match. It reports only whether a vessel was detected and never reveals the exact cell, vessel class, direction, or number of occupied cells.

Nuclear strike

Sink the enemy aircraft carrier to unlock one 3 × 3 strike. Every cell in its impact area is resolved through the normal hit, miss, and vessel-down logic.

Win the engagement

Damage every occupied section of a vessel to sink it. Destroy all five hostile vessels before the enemy destroys yours to secure the sector.
