Suika Defense

Merge by day. Defend by night. Survive as long as you can.

A cozy-but-strategic mashup of merge puzzles and tower defense. Every day you drop adorable little fighters into the arena and merge matching ones into bigger, stronger units. Then night falls, the horde marches in, and your units wake up to defend the base. Clear the wave, earn coins, upgrade — and do it all again as the nights get tougher.

How many days can you survive?

🍉 DROP & MERGE
Sling units into the board and combine matching ones to climb the tiers. Where you place them matters — a good board layout means a strong defense.

⚔️ DAY / NIGHT BATTLES
Build up your board in the calm of day, then hold the line at night. Every unit fires on its own — arrows, bombs, shotgun spreads and more — so your merges literally become your firepower.

💀 BOSS NIGHTS
Every 10th day a boss lumbers in, plants itself at your gate, and hammers your base until you take it down. Bring your best.

⭐ PERMANENT UPGRADES
Coins never reset. Spend them on lasting power boosts, extra units per day, and a tougher base. Die, come back stronger, push further.

🔁 ROGUELITE RUNS
Each run starts fresh at Day 1, but your upgrades and best-day record carry over. Leave mid-run and pick up right where you left off.

🏆 BEAT YOUR BEST
Chase your personal best and climb the global leaderboard. Every night survived is a new record to break.
