Tap the colorful screws stuck in the plates, and a Chibi Squid carries each one to the box of the same color. The trick is choosing which screw to pull first. Watching the plates come crashing down is pure joy!

Solve Hard stage 300 and your IQ is 195!

How to play IKA SCREW

  1. Tap a screw and a Chibi Squid carries it to the box of the same color. Two boxes sit side by side; each leaves once it holds 3 screws, and a new box arrives.
  2. Screws with no matching box right now go to the waiting tray. When a box of their color shows up, they hop in on their own.
  3. If the 5-slot tray fills up, you lose. Your first slip in each stage is safe, though: the tray gets one extra slot.
  4. Screws covered by another plate can't be pulled. Remove all the screws from a plate and it falls, freeing whatever was underneath.
  5. The colors of the next boxes are shown at the top. Look ahead before you pick a screw.

How the game goes

There are three courses: Easy, Normal and Hard. Clear 50 stages in Easy to open Normal, and 50 in Normal to open Hard. As you go, new screws make the order matter more and more: ice screws that melt after you pull others, "?" screws whose color stays hidden until nothing covers them, and key, lock and chain screws. Every 10th stage is a tough challenge stage that gives your IQ a big boost when you solve it.

IKA SCREW tips

Who it’s for

Great for anyone who loves planning-ahead puzzles or wants a quick brain workout in spare moments. The click of each screw landing in its box is oddly addictive.
