Normal 1 - The gauntlet
Use the one step spaces to avoid being shot as you make your way to the bottom area. Once you have the jewels deposited, collect the invincible, and you can now make your way back safely as the bullets can't hurt you.
Normal 2 - More explosions
After getting the bombs, make a space under the group of rocks so you can get to the wall they're guarding and blow your way in. Making the weak rocks tumble of off each other will break them and you can make your way to the far right. Now blow through the wall and get the key. Go through the door and the plunger will cause the anvil to open up the bottom room where you can clear up.
Normal 3 - Molten orb
Go up and press the 2 security switches. You will need to push a rock under the others so that they don't block your path. Now go down and press the right switch before the left, your trail will stop the growing walls from trapping you. You don't even need the orbs as you can pass over the tunnels at the other side instead of using the door. But they add to your score anyway.
Normal 4 - Monster hunter
Create a path between the rock monster and the mine. You can use the 9 rocks you get to destroy the 4 jewel monsters.
Normal 5 - Colony
Push the wall to the top right corner of the room your in. This will lead the monster into the mine later. Now use the tunnel to approach the monster from below. Collect the super jewels and the monster will go through the tunnel and eventually blow itself up on the mine. Once you've deposited 15 jewels, go to the small room with 2 teleporters close together and blow one of them up. After this step into this to go to the teleporter at the left. You can now travel over the tunnel, go right and pass over the soil. You will need to pass over a second set of soil to reach the exit.
Normal 6 - Careful push
Push the first wall 2 spaces to the left, and go around to the other side of it. Now push it into the spring and then into the socket. There's now 5 more pushable walls. Push the top one as far right as it will go. Now go around so you can push it down, then left, then down to the socket. The other 4 should be much easier to guide into the 4 sockets.
Now you have 7 more pushable walls. Push the very top, very bottom and center wall into the sockets directly to the side of them. Use another 3 to complete your path to the exit and whirlpools. You can get the super jewels now. Push the final wall into the socket on the right for the last jewels.
Normal 7 - Rock complex
This level isn't as hard as it looks. There's no absolute strategy for this other than to make sure the explosive rocks don't blow any jewels up. There's some power ups to make your journey easier but as usual, avoid the glasses.
Normal 8 - Tunnel journey
You can't do anything in the tunnel, you need to be over it. Use the openings inside the complex to get on top of it but avoid the monsters on the way there. Now you can get the jewels and the monsters won't hurt you as they're still inside it.
Normal 9 - 4 walls
You need to use the gunners to blow the walls and get to the jewels. As long as your careful not to shoot a C4 you should be fine. Move a gunner back behind the strong wall where it started when you're finished with it to prevent it shooting.
Normal 10 - Time keeper
You have to start by moving down. As you get to the clock, move onto it. This will stop the rock that's falling above you. Now get the 3 orbs as once time resumes, the rock will destroy them. Press the clock again to give you the full 7 seconds before heading to the invincible. Frozen time will prevent the rocks from falling and trapping you. Now head into the mine and get the jewels. Remember that while time is stopped, your invincible will never expire. Lastly you need to make your way to the exit. You need to be careful with the rock monsters. While they can't hurt you their rocks can block you. If need be, let time resume to let it move before stepping over the 5 seconds clock.
Normal 11 - Triplication
Firstly create a path the the sides and underneath of the triplicator underneath the bomb. When you drop the bomb in you will now get 3 bombs back. Use the bombs to blow your way into the bottom left room from the top. Now create paths around the triplicator and the inverter so that you can push the rocks scattered around the level into the inverter. A rock here will invert to a jewel and then multiply into 3. You have more rocks than you need so it should be simple from here.
Normal 12 - Lake pass
Go through the growing walls area into the water. You can surface for air where the jewels are while gathering the auto-jewels and pressing the plunger. Once you've passed the depth switch its just a case of clearing the jewels up while avoiding the monsters.
Normal 13 - Ice mines
You'll need the shield before wandering into the ice. Once you've slipped to the bottom, go right; the shield will get you through the mine. From the space where the mine was, go up and past the ice and mines back to soil. Once you've pressed the depth switch, the ice that's underwater is no longer slippery. You can use this to navigate to the other areas and clear up the jewels and reach the exit.
Normal 14 - Feed the monsters
Collecting the 30 auto-jewels will give you access to the security switch which will open up the room full of inverse jewels and mouth monsters. You don't want any inverse jewels so stay alert while the monsters eat them.
Once you can pass through the one step, you have 4 monsters to pass. A simple way of doing this is creating a path upwards to their area from the rightmost whirlpool then go back onto the whirlpool for cover. If you wait a few moments the monsters will settle to moving around the sides and you should be able to find a gap to safely pass through.
Normal 15 - Feed the monsters 2
The same as the previous level bar one difference, the inverse jewels are auto-jewels this time and you want them too! After pressing the security switch you need to collect quite a few jewels while avoiding being eaten at the same time.
Normal 16 - Prevention
Destroy the slow homing monster with a rock. Collect at least one of the peridots. With peridots in your trail, you are safe to collect the alcohol and magic glasses without getting the nasty side effects of them. No go into the mine area and gather the super jewels or as many as you need.
Normal 17 - Trail problem
Like the name suggests this level has more jewels than your trail can cope with. You must first start by collecting the 5 jewels above you. Now go left for the next 5 jewels and down for 5 more and the break jewel limit. Once you have the break jewel limit, head back up quick as your trail will prevent the jewels above you from falling, you will be forced to collect 1 though. Now let the other jewels drop so you can get the other break jewel limit without collecting the 4 jewels. Now head right going past everything until you get to the soil. You can now pass the trail doors and get the auto-jewels and use the teleporter to get to the exit.
Normal 18 - Undead hunter
Not too much to say here. There are more than enough ghost pills to get you past all the rocks and walls to collect the jewels. As long as you don't hang about there should be no problem.
Normal 19 - Mine field
Start by guiding the most central monster into the mines underneath the room with the whirlpool (a convenient place is make a path between the mines so the monster will try and move into one of them as it tries to turn). The monster at the bottom can be guided to the mine to the left of the exit, opening this up for later. Finally take the last monster to the mine that will get you to the jewels.
Normal 20 - Kamikaze
After hitting the return point you start near, run straight into the mine that leads you to the exit. Once you respawn, guide the monster to the nearest mine leading to the bomb. Now using the return points, run into the top left mine, and the other 3 mines leading to 3 auto-jewels each. Note: do NOT kill yourself while you have a trail of jewels as they will be lost. You can use the bomb to get to 4 auto-jewels by placing it on the wall between the 2 rooms with 2 auto-jewels each.
Normal 21 - Deep diving
This level is completely underwater so you air supply is very limited. Collect the invincible and bombs that start around you and then kill the water monsters. The other 2 invincibles in the corners will give you more time to get the jewels. You can collect all the invincibles at once since you will still get 3 invincibles worth of time regardless. Use the bombs to get to the other jewels.
Normal 22 - Weightlifting
You can tackle either the left or right side first. Use a balloon pad to lift a rock higher than the wall so it can be pushed. When you drop the rock onto the spring the jewel will stop it (don't collect the jewels until they've been used to stop rocks being sprung!). For this you need to make a path down from where the rock will stop beforehand so it will drop and can be pushed onto the monster.
Normal 23 - Underground
After you press the security switch you will need to be quick as the monsters will chase you. Once you pass onto the corner piece of the tunnel, move left one or two spaces. The monsters will go on, turn around and go under the tunnel you're on. The flame monster will blow itself up while the jewel monster will head back. This gives you time to carefully create a route the monster will follow, and take the route to the orange security mine. The monster must hit it from below so you get 9 jewels.
Now you can enter a set of tunnels from the bottom left area, go and collect the invincible which can be used to destroy the purple security mines.
Normal 24 - Explosive line
Use the invincibles to destroy the monster. Bear one thing in mind. If a monster is destroyed with only one space of soil between itself and the open space around the C4s, the jewels will manage to trigger the C4s. You will need to guide these monsters towards the center by a little.
Normal 25 - Eternal gem
This level is big but easy. The real challenge is beating the preset high score. If you want to beat the record, remember that the key to your score in this level is your trail.
