Battleship meets Bingo in 3D

Free browser strategy game

A tank duel won by deduction, not reflexes

Tank Echo combines turn-based tank combat with Battleship-style deduction. Terrain limits line of sight, while every missed shot returns a row, column, or diagonal clue that narrows down the hidden enemy. Play solo against bots or challenge another commander in your browser.

How to play Tank Echo

1. 01

   Choose a firing line

   Move through the 3D battlefield and fire only at cells your tank can reach through clear line of sight.

2. 02

   Read the echo

   A miss still reveals whether the enemy is aligned with the shot by row, column, or diagonal.

3. 03

   Find the hidden tank

   Combine each clue with terrain and prior shots, then predict the enemy's position before they find yours.
