About this game

You are the lock keeper on duty at a cascade of flood canals, and the water is rising fast. The control board flashes the colour of the canal where the flood is surging right now. Your job is simple to grasp and hard to master: tap only the gates of that active colour once they climb into the red zone, and drop the sluice before the chamber tops out at 100%.

Gates appear across a 3x3 grid in three canal colours: blue, green, and amber. Only the gates of the active flood keep rising. Hit the right gate in the red zone and you score points while your combo multiplier grows. Tap a gate of the wrong colour, tap one that has not reached the danger line yet, or let a chamber overflow, and you lose one of your three dam-strength markers and reset your combo. Lose all three and the round ends with a big OVERFLOW.

The pressure never sits still. Every few seconds the board switches to a new active colour, so you have to stay sharp and read the banner at a glance. As your score climbs, the water rises faster and new gates arrive more often, so the pace tightens smoothly the longer you last. There is no separate difficulty menu; the challenge builds inside a single run.

Everything here is about reaction and focus. One good session sets a new best score and a new best combo, and both are saved on your device so your shift picks up where it left off. Short sound effects mark each closed gate and each overflow, and you can turn sound on or off in Settings.

Features:
- Fast tap-reaction gameplay on a 3x3 gate grid
- Follow the active flood colour and clear gates in the red zone
- Combo multiplier that rewards clean streaks
- Three dam-strength markers per run
- Rising tempo that ramps up as your score grows
- Best score and best combo saved locally
- Sound toggle in Settings
- Portrait orientation, works offline

Step up to the control board, watch the colour, and keep the water in check for as long as you can.
Tap the glowing gates of the active canal before the water spills over.
