Tetris is a classic puzzle game invented by Russian programmer Alexey Pajitnov in 1984. The objective is to arrange falling blocks of different shapes to complete horizontal lines, which then disappear and award points. The game speeds up over time, testing your reflexes and spatial reasoning skills.
In Tetris, your main goals are:
There are 7 classic Tetris blocks (tetrominoes), each made of 4 squares:
████
Four squares in a straight line, perfect for clearing 4 lines at once
██
██
2×2 square, cannot rotate, good for filling square gaps
▀█▀
█
T-shaped block, very versatile, can be rotated to fit various spaces
██
██
S-shaped block, complements Z-block, good for stair-like gaps
██
██
Z-shaped block, complements S-block, requires advance planning
█
███
J-shaped block, protrudes on the left, good for left-side gaps
█
███
L-shaped block, protrudes on the right, good for right-side gaps
When playing on mobile or tablet, virtual buttons appear at the bottom:
Tetris uses the classic scoring system - the more lines you clear at once, the higher your score:
💡 Scoring Tip: Try to stack blocks and clear 4 lines at once for maximum scoring efficiency! This is called a "Tetris" and is the most valuable move in the game.
Every 10 lines cleared increases your level by 1. Higher levels mean:
Try to keep the bottom of the play area as flat as possible, avoiding uneven terrain. A flat bottom gives you more placement options and reduces hard-to-fill gaps.
Reserve a vertical channel one block wide on one side (usually the right) specifically for I-blocks. This lets you easily clear 4 lines at once for high scores.
Always check the "Next" preview in the top right corner. Plan your current block placement with the next block in mind, leaving appropriate space.
Don't use the spacebar for hard drop too early. Confirm the best placement position first. Give yourself more thinking time, especially early in the game.
Prioritize filling and clearing bottom rows to prevent excessive stacking. The higher the bottom stacks, the less room you have to maneuver.
T-Spin is an advanced technique where you cleverly rotate the T-block to fit into seemingly impossible spaces. While this game doesn't award separate T-Spin bonuses, this skill helps you fill complex gaps.
Don't settle for single line clears. Learn to accumulate blocks and create opportunities to clear multiple lines at once. Especially aim for 4-line "Tetris" clears - the most efficient scoring method.
If you inevitably create gaps, don't panic. Remember the gap's position and shape, and patiently wait for the right block to fill it. Sometimes you need to temporarily stack blocks above gaps and deal with them later.
As levels increase, blocks fall faster. Practice quick operations early to build muscle memory. Even at low levels, try using the down arrow to accelerate and adapt to high-speed gameplay.
Stack blocks on both sides while keeping the middle relatively low. This gives you more operating space and time to adjust block positions. This strategy reduces errors especially at high speeds.
Many beginners only focus on the current block, ignoring the "Next" preview. This leads to poor placement that creates difficulties for the next block.
Pressing spacebar before confirming the position causes blocks to land in wrong places. Move into position first, rotate, then use hard drop.
Leaving 1-2 square irregular gaps in corners or the middle. These gaps are hard to fill and cause increasingly high stacks.
Excessive middle stacking severely limits block movement and rotation space, easily ending the game. Keep the middle lower with moderate side stacking.
While the I-block channel strategy is good, don't rely on it too much. If you wait too long for an I-block, other areas will stack too high. Stay flexible.
🎯 Practice Advice: Tetris requires extensive practice. Don't get discouraged by frequent game overs early on - each failure is a learning opportunity. With practice, you'll notice improvements in reaction speed, spatial awareness, and decision-making!
